Four Ag(I) complexes, [Ag(L1)2](NO3) (1), [Ag(L2)(NO3)] (2), [Ag(L3)3](NO3) (3), and [Ag(L4)2](NO3) (4), with ligands derived from halo-containing cyanoanilines (L1 = 4-amino-3fluorobenzonitrile, L2 = 4-amino-3-chlorobenzonitrile, L3 = 4-amino-3-bromobenzonitrile, L4 = 4-amino-2-bromobenzonitrile) were synthesized and characterized by C, H, and N elemental analysis, IR and 1H NMR spectroscopy and single crystal X-ray diffraction. Complexes 1–4 crystallized in the triclinic space group C2/c, P2(1)/n, P-1 and C2/c, respectively. In 1 and 4, Ag+ is four-coordinate with L1 or L4 to form 1-D ∞{[Ag(L1/L4)2]+} polymeric cations. In 2, Ag+ is three-coordinate by two L2 ligands and one NO3? ligand to form a 1-D ∞{[Ag(L2)(NO3)]} zigzag chain. In 3, Ag+ is four-coordinate by L3 to form a dinuclear [Ag(L3)3]+ cation. The NO3? is a 4-connector bridging group in 1 and 3 and a 5-connector bridging group in 2 and 4. The intermolecular hydrogen bonds and Ag?O weak interactions play important roles in forming 3-D networks of 1–4. The antibacterial activities for 1–4 were evaluated against Bacillus subtilis, Staphylococcus aureus and Escherichia coli with MTT method. The antibacterial results indicated that 2 showed the best inhibitory activity against the test bacterial strains, and was as potent as chloramphenicol. 相似文献

A new chloro- and methoxo-bridged Cu(II) coordination polymer, [Cu2(2-APM)2(μ-Cl)2(μ-OCH3)2]n·CH3OH (1), was prepared using in situ formed chloride by the decomposition of cyanuric chloride and 2-aminopyrimidine (2-APM) as a ligand in methanol. Its solid-state structure has been characterized by elemental analysis and single crystal X-ray diffraction. X-ray crystallographic studies reveal that this compound has an extended 2-D supramolecular architecture directed by strong hydrogen bonds and aromatic π–π stacking interactions. Compound 1 shows an antiferromagnetic coupling exchange with coupling constants of ?58.2 and ?41.4 cm?1 between adjacent copper(II) ions, in agreement with the intermetallic distances of 3.0405(5) and 3.6073(5)?Å found in the crystal structure. 相似文献

Four Cu(II)/Co(II) coordination polymers, [Cu(L)(BDC)(H2O)]·3H2O (1), [Cu(L)(DNBA)2] (2), [Co(L)2(DNBA)2] (3), and [Co(L)(NIPH)(H2O)]·H2O (4) (H2BDC = 1,4-benzenedicarboxylic acid, HDNBA = 3,5-dinitrobenzoic acid, H2NIPH = 5-nitroisophthalic acid, L = N,N′-di(3-pyridyl)sebacicdiamide), have been synthesized under hydrothermal conditions. The structures of 1–4 have been determined by single-crystal X-ray diffraction analyses and 1–4 were further characterized by infrared spectroscopy and thermogravimetric analyses. Complex 1 is a 2-D polymeric layer with a 4-connected sql topology. Complex 2 displays a 1-D zigzag chain. Complex 3 possesses a 1-D double-chain structure. Complex 4 exhibits a ribbon chain based on the 1-D [Co–L]nmeso-helical chain. Adjacent layers for 1 and adjacent chains for 2–4 are further linked by hydrogen bonding or π–π stacking interactions to form 3-D supramolecular networks. The differences of carboxylates and metal ions show significant effect on the ultimate architectures of the four complexes. Thermal stabilities, fluorescent properties and photocatalytic activities of 1–4 were also studied. 相似文献

Employing 1-(2-methoxybenzyl)-2-(2-methoxyphenyl)-1H-benzimidazole (bpb) as a monodentate ligand, a new greenish-blue copper(II) complex, [Cu(bpb)2(NO3)2] (1a), has been synthesized. 1a has been characterized analytically and spectroscopically. The X-ray crystal structure of 1a reveals that it adopts a cis disposition with respect to the ligands. The solid state structure of 1a is stabilized by intramolecular offset face-to-face π–π stacking. Non-covalent supramolecular edge-to-face C–H?π interactions with neighboring molecules give 1-D supramolecular chains that further lead to the formation of an assembled 3-D supramolecular metal-organic framework via hydrogen bonding interactions. 1a shows blue fluorescence most likely due to intramolecular offset face-to-face π–π stacking. At room temperature, 1a is one-electron paramagnetic. It shows a rhombic EPR spectrum with g1 = 2.12, g2 = 2.42, and g3 = 2.52 in the solid state at liquid nitrogen temperature. In cyclic voltammetry, 1a displays a one-electron oxidative Cu(II)/Cu(III) couple. Our DFT calculations, corroborate the observed experimental results of 1a. 相似文献

Two cadmium(II) coordination compounds, [Cd3(CH3CO2)4(ad)2(CH3CN)2]n (1) and [Cd3(5-SIP)2(H-ad)2(H2O)6]n (2) (H-ad = adenine and 5-SIP = 5-sulfoisophthalate), were synthesized and characterized. Compound 1 features a two-dimensional (2-D) layered structure based on linear trinuclear [Cd3(CH3CO2)4] units bridged by monoanionic adenine ligands. In 2, the 5-SIP3? ligands link Cd(II) ions to form a one-dimensional (1-D) ladder, which is further linked by neutral adenine ligands to give a 2-D layered structure. In both structures, the carboxylate ligands link Cd(II) ions to form low-dimensional structures, which are further connected by adenine ligands to give high-dimensional structures. Compounds 1 and 2 exhibit emissions centered at 382 and 416 nm, respectively, which can be attributed to the ligand centered π–π* transition. 相似文献

The paucity of coordination entities bearing (E)-N,N′-bis(heteroaryl)iminoisoindolines has prompted us to investigate coordination modes and supramolecular features of (E)-N,N′-bis(2-pyridyl)iminoisoindoline (2-pyimiso), a versatile iminobis(pyridyl) ligand. In this article we report the synthesis, spectroscopic characterization and crystal structure analysis of two Cd(II) : 2-pyimiso (1?:?2) bis-adducts, [CdX2(2-pyimiso)2] [X = Cl (1) or NCS (2)]. Our X-ray structural results reveal that 1 exhibits distorted tetrahedral coordination (four-coordinate geometry index τ4 = 0.92), whereas 2 displays six-coordinate Cd(II) and two four-membered chelate rings (bite angles = 52.5°), each comprising one Cd–Npy [2.247(2) Å] bond and one Cd?Nimine [2.809(21) Å] secondary interaction. Remarkably, in 2 each 2-pyimiso unit binds to Cd(II) according to an unusual bidentate coordination. The contributions of the Cd–N and Cd–Cl bond valences to the total metal valence for both 1 and 2 have been evaluated to confirm the coordination modes of 2-pyimiso, which can be interpreted in terms of Jørgensen’s principle of symbiosis. X-ray structure and Hirshfeld surface analyses have shown that the crystal structure of 1 is determined by two perpendicular 1-D chains formed by weak hydrogen bonds along the a- and c-axes, whereas the supramolecular architecture of 2 exhibits 2-D sheets parallel to the ab-plane interconnected by C–H?π interactions along the c-axis. A vibrational analysis of both products has been conducted at the DFT B3LYP-D3/LACV3P** level of calculation. 相似文献

Three pyrrolyl-substituted triaryltriazoles, 3-(N-methyl-2-pyrrolyl)-4-(p-R-phenyl)-5-(2-pyridyl)-1,2,4-triazole (L1: R = MeO; L2: R = Cl; L3: R = Br), and their mononuclear iron(II) complexes, trans-[Fe(L1–3)2(NCS)2]?2MeOH (1: L1; 2: L2; 3: L3), have been synthesized and characterized by elemental analysis, FT-IR, ESI-MS, and single-crystal X-ray crystallography. Crystallographic studies revealed that 1–3 are isomorphous and crystallize in the triclinic space group P-1. All the complexes have a similar octahedral [FeN6] core with two trans-NCS? ions. Each ligand adopts a chelating bidentate coordination mode via the pyridyl N and one N of the triazole. Intermolecular O–H?O hydrogen bonding and C–H?π interactions link the molecules of 1–3 to form a 1-D chain or 2-D framework. Variable-temperature magnetic susceptibility measurements indicated that all the complexes remained in a high-spin state from 1.8 to 300 K and had a weak antiferromagnetic interaction. 相似文献

Three copper(II) complexes, [Cu(L1)(H2O)(ClO4)]·0.5H2O (1), [Cu(L2)(H2O)(ClO4)]·0.5H2O (2), and [Cu(L2)(NCNC(OCH3)NH2)]ClO4 (3), where HL1 = 4-bromo-2-(-(quinolin-8-ylimino)methyl)phenol and HL2 = 1-(-(quinolin-8-ylimino)methyl)naphthalen-2-ol, have been prepared and characterized by elemental analysis, IR, UV–vis and fluorescence spectroscopy and single-crystal X-ray diffraction studies. The copper(II) centers assume five-coordinate square-pyramidal geometries in 1 and 2, whereas square planar copper(II) is present in 3. A methanol molecule has been inserted in the pendant end of the ligated dicyanamide in 3. Various supramolecular architectures are formed by hydrogen bonding, π?π, C–H?π, and lp?π interactions. 相似文献

Two new complexes, {[PbL(NO3)2H2O]H2O}n (1) and [BiL2(NO3)2]NO3 (2), based on (E)-3-chloro-6-[2-(pyrazin-2-ylmethylene)hydrazinyl]pyridazine (L) were synthesized and characterized by IR spectra, single-crystal X-ray diffraction, and elemental analyzes. X-ray single crystal diffraction experiments of 1 and 2 display that extensive hydrogen bonds and π…π stacking interactions construct the 1-D infinite chain {[PbL(NO3)2H2O]H2O}n and [BiL2(NO3)2]NO3 into two 3-D supramolecular frameworks. Interestingly, pure phase PbO nano-particles were synthesized by thermolysis of 1 and characterized by scanning electron microscopy and X-ray powder diffraction analyzes. Furthermore, antioxidant activities of L, 1, and 2 were also studied. 相似文献

Ten new complexes, [Cu2(L1)(NO3)2]·2H2O (1), [Cu4(L1)2]·4ClO4·H2O (2), [Cu2(L1)(H2O)2]·(adipate) (3), [Cu6(L1)2(m-bdc)4]·2DMF·5H2O (4), [Cu2(L1)(Hbtc)]·5H2O (5), [Cu2(L1)(H2O)2]·(ntc)·3H2O (6), [Co2(L2)]·[Co(MeOH)4(H2O)2] (7), [Co3(L2)(EtOH)(H2O)] (8), [Ni6(L2)2(H2O)4]·H2O (9) and [Zn4(L2)(OAc)2]·0.5H2O (10), have been synthesized. 1 displays a [Cu2(L1)(NO3)2] monomolecular structure. 2 shows a supramolecular chain including [Cu2L1]2+. In 3, two Cu(II) ions are connected by L1 to form a [Cu2(L1)(H2O)2]2+ cation. In 4, the m-bdc anions bridge Cu(II) ions and L1 anions to form a layer. Both 5 and 6 display 3-D supramolecular structures. 7 consists of both [Co2L2]2? and [Co(MeOH)4(H2O)2]2+ units. 8 and 9 show infinite chain structures. In 10, Zn(II) dimers are linked by L2 to generate a 3-D framework. The magnetic properties for 4 and 8 and the luminescent property for 10 have been studied. 相似文献

Four 3d–4f heteronuclear complexes, [(ZnL)2La(OAc)2]·ClO4·2CHCl3 (1), [(ZnL)2La(OAc)2]·CF3SO3·H2O (2), [ZnNd(L)(Py)(NO3)3] (3), and [ZnGd(L)(OAc)(NO3)2] (4) (Py = pyridine; H2L = 6,6′-dimethoxy-2,2′-[ethylenedioxybis(nitrilomethylidyne)]diphenol), have been prepared by one-pot reaction of H2L with zinc(II) acetate, lanthanide(III) ions and Py. Although the heterobinuclear complexes 1–4 are prepared in the same reaction condition, the Py does not coordinate to Zn(II) of 1, 2, and 4. Instead, the bridging μ-acetato ligand is present. The coordination of the Py in 3 leads to smaller distortion of square pyramidal coordination site of Zn(II), the higher coplanarity between the planes of ZnO(phenoxo)2 and LnO(phenoxo)2, and the longer Zn?Ln distance compared with 4. The luminescence properties of 1–4 have been discussed. The ligand (L2?) can sensitize NIR luminescence of Nd(III) ions. 相似文献

Hydrothermal reactions of 1,3-bis(1,2,4-triazol-1-yl)benzene (btb) and M(NO3)2 (M = Co2+ (1), Cu2+ (2)) afforded two new coordination polymers, [Co(btb)2(NO3)(H2O)]n·NO3·H2O (1) and [Cu(btb)2(NO3)2]n (2), respectively. Single-crystal X-ray diffraction reveals that 1 crystallizes in the space group P21/m and 2 crystallizes in the space group Pī, both showing a double-stranded chain structure. The 1-D chains are interconnected via π?π interactions to lead to 2-D ladder-like supramolecular architectures. In addition, magnetic behavior and thermal stability of 1 and 2 have been investigated. For 1, weak antiferromagnetic interactions are observed at low temperature, and the data obey the Curie–Weiss law χM = C/(T?θ), with C = 3.22 cm3·mol?1·K and θ = ?10.39 K. For 2, the decrease of the χT vs. T curve at low temperature is the result of intermolecular antiferromagnetic magnetic interactions. 相似文献

Rare-earth complexes of the general formula [Ln(H2L1)2(NO3)3] [Ln = Gd (1), Ho (2) or Nd (3)] were prepared from an o-vanillin derived Schiff base ligand, 2-((E)-(1-hydroxy-2-methylpropan-2-ylimino)methyl)-6-methoxyphenol (H2L1). The single-crystal X-ray diffraction studies and SHAPE analyses of the Gd(III) and Ho(III) complexes show that the complexes are ten-coordinate and exhibit distorted tetradecahedron geometries. The phenolate oxygen-bridged dinuclear complex, [Ce2(H2L1)(ovan)3(NO3)3] (4, ovan = monodeprotonated o-vanillin), was obtained from the reaction of Ce(NO3)3?6H2O with H2L1. X-ray analysis revealed that hydrolysis of H2L1 occurred to yield o-vanillin, which bridged two cerium atoms with the Ce?Ce distance equal to 3.8232(6) Å. The Ce(III) ions are both ten-coordinate, but have different coordination environments, showing tetradecahedron and staggered dodecahedron geometries, respectively. With proton migration occurring from the phenol group to the imine function, complexation of the lanthanides to the ligand gives the Schiff base a zwitterionic phenoxo-iminium form. 相似文献

Two new coordination polymers with an asymmetric dicarboxylate and 4,4′-bipyridine ligand, {[Co(bpy)(H2O)4]·(cpa)·0.5H2O}n (1) and {[Ag(cpa)(bpy)][Ag(bpy)]·4H2O}n (2) (H2cpa = 4-(2-carboxyethyl)benzoic acid, bpy = 4,4′-bipyridine), have been hydrothermally synthesized and characterized by elemental analysis, FT-IR spectroscopy, and single-crystal X-ray diffraction. Compound 1 displays a linear chain with guest molecule (cpa)2? ions existing in the structure. Compound 2 contains two independent units, [Ag(cpa)(bpy)]– (A) and [Ag(bpy)]+ (B), which form a 1-D + 1-D structure. A shows a 1-D chain structure bearing hooks formed by the carboxylates and organized into a tubular structure by hydrogen-bonding interactions. B has linear chains formed from Ag+ and bpy. The A and B chains co-crystallize with waters of crystallization to provide two linear [Ag(bpy)]+ chains embedded in the tubular structure formed by A via π…π stacking contacts. In 1 and 2, hydrogen-bonding and π…π stacking interactions connect the discrete 1-D chains into 3-D supramolecular structures. The fluorescent properties, TG analysis, and X-ray powder diffraction patterns for 1 and 2 were also measured. 相似文献

Four novel Schiff base ligands and their copper(II) complexes, [Cu(L1)2] (1), [Cu(L2)2] (2), [Cu(L3)2] (3), and [Cu(L4)2] (4), were synthesized and characterized by elemental analyses, FT-IR, and UV–Vis spectroscopy. The ligands were synthesized from the condensation of 2-methoxyethylamine with various salicylaldehyde derivatives (x-salicylaldehyde for HLn, x = H (n = 1), 5-Br (n = 2), 3-OMe (n = 3), and 4-OMe (n = 4)). The molecular structures of 1, 2, and 3 were determined by the single crystal X-ray diffraction technique. The redox behavior studies of the complexes in acetonitrile display the electronic effects of the groups on the redox potential. The antioxidant activity of the Schiff base ligands and their Cu(II) complexes was evaluated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging method and FRAP assay. Furthermore, the in vitro anticancer activity of compounds was screened, including MTT and migration assays against gastric cancer cell line (MKN-45). The results show that all ligands and complexes have antioxidant and anticancer activity in a concentration-dependent way. 相似文献

Two multinuclear Co(II) complexes, [{Co(L)(i-PrOH)}2Co(H2O)]?2CH3CN (1) and [{Co(L)(μ-OAc)Co(MeOH)2}2]?2CH3COCH3 (2), have been synthesized with a new asymmetric Salamo-type ligand (H3L = 6-hydroxy-6′-ethoxy-2,2′-[ethylenediyldioxybis(nitrilomethylidyne)]diphenol). The Co(II) complexes were obtained by different solvents, and the structures are completely different. In the Co(II) complex 1, the ratio of the ligand H3L to Co(II) atom is 2 : 3 and the Co(II) ions are all five-coordinate with trigonal bipyramidal geometries. In the Co(II) complex 2, the ratio of the ligand H3L to Co(II) atom is 2 : 4. Two central Co(II) ions are six coordinate with distorted octahedral geometries and two terminal Co(II) ions are five coordinate with distorted trigonal bipyramidal geometries. Self-assembling of an infinite 1-D supramolecular chain is formed by C–H?π interactions in 1. Interestingly, an infinite 2-D-layer plane structure is formed by the self-assembling array of 2 linked by C–H?π interactions. 1 and 2 exhibit blue emissions with the maximum emission wavelengths λmax? = 403 and 395 nm when excited at 330 nm. 相似文献

A mixed-valence 2-D Cu(I/II) complex, [{Cu(II)(dmen)(μ-Cl)(μ1,5-dca)}{Cu(I)(μ1,5-dca)}]n (1) (dmen = N,N-dimethylethylenediamine, dca = dicyanamide = [N(CN)2]?), has been synthesized by in situ partial reduction of Cu(II) to Cu(I) using benzoin (2-hydroxy-1,2-di(phenyl)ethanone) as reductant. Complex 1 was characterized by spectroscopic techniques, single crystal X-ray diffraction, and low temperature magnetic measurements. Structural investigation reveals that 1 represents a mixed-valence 2-D coordination polymer formed by parallel 1-D [Cu(II)(dmen)(Cl)Cu(I)(μ1,5-dca)2]n chains running along the b axis, where chloride bridges Cu(II) ions of adjacent polymers through long connections (2.8401(1) Å) to form a 2-D network. The metal centers have two different geometrical environments (distorted square pyramidal and distorted trigonal planar geometries for Cu(II) and Cu(I), respectively). The Cu(II) ions in [Cu(II)(dmen)(μ-Cl)(dca)]n are interconnected through single chloride bridges while within the [Cu(I)(μ1,5-dca)]n units, the dca connects adjacent Cu(I) ions through μ1,5-dca bridges. Magnetic susceptibility measurements reveal weak ferromagnetic interactions (J = +0.3 cm?1) within the chlorido-bridged Cu(II) regular chain present in 1. Simultaneous presence of μ1,5-dca and single chlorido bridges with ferromagnetic coupling is believed to be unique in mixed-valence Cu(I)/Cu(II) complexes. 相似文献

Assembly of orotic acid (H3Or, 1,2,3,6-tetrahydro-2,6-dioxo-4-pyrimidinecarboxylic) and Cd(NO3)·6H2O yielded a coordination polymer, [(Cd(Hor)·2.5H2O)2]n (1), which has been characterized by X-ray single-crystal diffraction, TGA, and ?uorescence spectra. Single-crystal X-ray structural analyses reveal that 1 is a hydrogen-bonded binuclear Cd-orotate coordination polymer in which both Cd2+ ions have different coordination environments with identical distorted octahedral geometry. Crystal data for 1: monoclinic, space group P21/n, a = 7.0209(10) Å, b = 13.974(2) Å, c = 17.541(3) Å, β = 98.842(2)°, V = 1700.5(4) Å, Z = 4, R1 = 0.0269, wR2 = 0.0612, θmax = 25.960. The emission spectrum of the Cd-complex recorded with 265 nm excitation wavelength reveals the complex has strong blue luminescence with the peak maximum 420 nm (2.95 eV) as a result of the n–π* and π–π* transitions on the H3Or ligand. 相似文献

Five coordination polymers containing linear lanthanide–oxygen clusters 1–5 have been synthesized by a hydrothermal reaction of 3-(quinolin-8-yloxy) phthalic acid (H2L) with the respective lanthanide salt. The X-ray single crystal structural analyses revealed that these five crystalline materials belong to two isostructures with formulas [LnHL2(H2O)2]n (Ln1, where Ln = La 1, Ce 2, Pr 3) and [Ln(HL)(L)(H2O)]n (Ln2, where Ln = Nd 4, Sm 5), respectively, which are attributed to the effect of lanthanide contraction. In both structures, the lanthanide cations were bridged by two carboxyl groups of L2? through Ln–O bonds to form 1-D linear lanthanide–oxygen clusters, which were further connected by intermolecular π–π stacking interactions between quinolinyl units to generate 3-D supramolecular polymers with moderate luminescence and high thermal stability. 相似文献

To investigate the effect of the spacers of S-/O-bridged dipyridylamides on the structures of Co(II)/Zn(II) complexes, [Co(L1)(chda)]·1.5H2O (CP1), [Co(L2)(chda)] (CP2), [Zn(L1)(hip)]·DMA·2H2O (CP3), and [Zn(L2)(hip)]·2.8H2O (CP4) [L1 = N,N′-bis(pyridine-3-yl)thiophene-2,5-dicarboxamide, H2chda = trans-1,4-cyclohexanedicarboxylic acid, L2 = N,N′-bis(pyridine-3-yl)-4,4′-oxybis(benzoic) dicarboxamide, H2hip = 5-hydroxyisophthalic acid, DMA = N,N-dimethylacetamide], have been solvothermally synthesized. X-ray single-crystal diffraction shows that CP1 is a 2-D 3,5-connected network based on Co-L1 linear chains and (Co-chda)2 double chains. CP2 features a 1-D structure derived from 1-D wave-like (Co-chda)2 double chains decorated by terminal L2 ligands. CP3 and CP4 show wave-like (4,4) networks constructed by 1-D Zn-L1 zigzag and Zn-hip zigzag (for CP3)/linear (for CP4) chains. The effect of the spacers of S-/O-bridged dipyridylamides on the structures of the title complexes was discussed. Electrochemical behaviors of CP1–CP2 and solid-state luminescent properties of CP3–CP4 were studied. The luminescence investigations show that CP3 and CP4 are recycled fluorescent probes for environmentally relevant Fe3+ ions. The photocatalytic properties for the degradation of methylene blue (MB) under ultraviolet light irradiation of CP3–CP4 and the recyclable materials after fluorescent sensing Fe3+ ions (named CP3@Fe3+ and CP4@Fe3+) have also been investigated. 相似文献
