Four lanthanide supramolecular coordination compounds, [Eu(gly)2(phen)2(H2O)2](ClO4)3(phen)4 · H2O ( 1 ), [Eu2(APA)6(phen)2](ClO4)6(phen)4 · 3H2O ( 2 ), [Tb2(ABA)4(phen)4](ClO4)6(phen)4 ( 3 ), and [Eu2(AHA)4(phen)4](ClO4)6(phen)2 · 2H2O · 2C2H5OH ( 4 ) (gly = glycine, APA = 3‐aminopropionic acid, ABA = 4‐aminobutanoic acid, AHA = 6‐aminohexanoic acid, phen = 1, 10‐phenanthroline), were synthesized and characterized by single crystal X‐ray diffraction. Compound 1 has a 2‐D supramolecular layered structure of mononuclear coordination cations and free phen molecules connected via hydrogen bonding and π‐π stacking interactions. 2 forms a 3‐D supramolecular network by hydrogen bonding between binuclear coordination cations and free phen molecules, between coordination cations and lattice water molecules, and π‐π stacking interactions between free phen molecules. Compounds 3 and 4 form 2‐D supramolecular structures with π‐π stacking between coordinating phen molecules, and between free phen molecules hydrogen‐bonded to the binuclear coordination cations. The high‐resolution emission spectra show only one Eu3+ ion site in the title complexes. The aqueous solutions of the title complexes are all photochromic with the color of the solution changing from yellow to green when irradiated by mercury lamp. During the decoloration process, they return to yellow color. 相似文献

A series of mixed-ligand M(II) complexes containing 1,10-phenanthroline (phen) and 3-methylpyridine-2-carboxylic acid (3-mpaH) or 6-methylpyridine-2-carboxylic acid (6-mpaH), namely [Co(3-mpa)2(phen)]·3H2O ( 1 ), [Hg(6-mpa)2(phen)]·2H2O ( 2 ), [Mn(6-mpa)2(phen)]·2H2O ( 3 ), [Co(6-mpa)2(phen)]·H2O ( 4 ) and [Ni(6-mpa)2(phen)]·H2O ( 5 ), were synthesized for the first time. Among them, 1 was obtained as single crystals. The structural characterization for 1 was conducted using X-ray diffraction and that for 2 – 5 using mass spectrometry. The IC50 values for α-glucosidase inhibition of 1 – 5 were obtained as 0.161 to >600 μM. The spectral properties were also investigated using Fourier transform infrared and UV–visible spectra. Furthermore, to investigate the geometrical parameters, spectral and electronic properties and second- and third-order nonlinear optical parameters for 1 – 5 , density functional calculations were applied. 相似文献

Two coordination complexes, namely [Co(phen)(H2O)L]·H2O and [Ni2(phen)2(H2O)2L2]·4H2O (phen = 1,10-phenanthroline, H2L = 1,3-adamantanedicarboxylic acid) have been hydrothermally synthesized and structurally characterized by single crystal
X-ray diffraction. [Co(phen)(H2O)L]·H2O consists of 1D chains of the complex plus lattice H2O molecules. Interchain hydrogen bonds and π–π stacking interactions assemble the 1D chains into 2D layers. [Ni2(phen)2(H2O)2L2]·4H2O is a binuclear complex which is assembled into a 3D supramolecular structure by strong hydrogen bonds and π–π stacking interactions.
Both complexes were characterized by physico-chemical and spectroscopic methods. 相似文献

[Cd2(phen)2(DPZDA)2(H2O)2] · 8H2O (1) and [Zn(phen)(DPZDA)(H2O)] · 2H2O (2) have been synthesized by reaction of Cd(NO3)2/Zn(NO3)2 with phen and DPZDA (where phen = 1,10-phenanthroline, H2DPZDA = 3,5-dimethyl-2,6-pyrazinedicarboxylic acid) in aqueous ethanol solution. Elemental analysis, IR spectra, thermal analyses and X-ray single crystal diffraction were carried out to determine the composition and crystal structure of 1 and 2. In 1, a 2D supramolecular network containing a novel metal-water decamer were formed by hydrogen bonds. In 2, a 2D supramolecular structure was constructed from hydrogen bonds and π·· · π interactions. Moreover, 1 and 2 displayed photoluminescent properties in the blue range at room temperature. 相似文献

Two novel manganese(II) complexes, [Mn(phen)2N3·H2O]ClO4·H2O and Mn(phen)2(N3)2 have been synthesized by the reaction of Mn(ClO4)2·6H2O and Mn(CH3CO2)2·4H2O with NaN3 and phen in EtOH/H2O solution, respectively (where phen = 1,10-phenanthroline). Their crystal structures have been determined by X-ray diffraction. Both complex molecules have distorted octahedral geometry and two 1,10-phenanthroline molecules chelate to a Mn(II) atom with a cis-configuration. To [Mn(phen)2N3·H2O]ClO4·H2O, one nitrogen atom from an azide anion and one oxygen atom from a water molecule cis-coordinate to the Mn(II) atom while two nitrogen atoms occupy cis positions in Mn(phen)2(N3)2. These complexes are versatile precursors for the design of heteropolymetallic systems. 相似文献

Cobait(Ⅱ) nitrate reacted with 1,10-phenanthroline (phen) and 5-sulfosaiicylic acid (H3ssal) to yield the cobait(Ⅰ) complex [Co(phen)2(H2O)2](Hssal)o4H2O (1) and the reaction of 1 with copper acetate led to a novel complex [Co(phen)(H2O)4][Cu2(ssal)2(phen)2]·5H2O (2). These two complexes were cationanion species and the cationic motif [Co(phen)2(H2O)2]^2+of 1 could be converted to [Co(phen)(H2O)4]^2+ in the formation process of new anion [Cu2(phen)2(ssal)2]^2- of 2. In both complexes abundant hydrogen bonds construct different supramolecular architectures, thus the conversion reaction can provide a new path to create novel supramolecular network. 相似文献

Three new copper(II) complexes with isonicotinic acid N-oxide (HL) and 1,10-phenanthroline (phen) as ligands, [Cu(L)(phen)(H2O)]2(NO3)2···2H2O (1), [Cu(L)(phen)(H2O)]2(ClO4)2···2H2O (2), and [Cu(L)(phen)Br]2- [Cu(L)(phen)(H2O)]2Br2···6H2O (3) have been synthesized and structurally characterized. The structures of all three complexes feature a Cu2 dimer formed by two Cu(II) ions interconnected by two bridging ligands. Each copper(II) ion has a distorted square pyramidal coordination geometry with elongated axial coordination by an aqua ligand or halogen anion. The isonicotinic acid N-oxide anion is bidentate, being coordinated to two Cu(II) ions through its N-O oxygen and one of its carboxylate oxygen atoms. Magnetic susceptibility measurements show a Curie–Weiss paramagnetic behavior characteristic of one unpaired electron for a copper(II) ion for all three complexes. 相似文献

Two three-dimensional supramolecular water architectures, [Zn(phen)3]2·[Zn(C10H16O4)·(H2O)3]·(C10H16O4)2·20H2O (1) and [Co(phen)3]2·[Co(H2O)6]·(C10H16O4)3·30H2O (2) [phen = 1,10-Phenanthroline, C10H16O4 = sebacic dianion], have been synthesized and characterized by IR, elemental analysis, thermogravimetric analysis, and single-crystal X-ray diffractions. The two structures both contain extensive hydrogen bonding between water molecules as well as between water molecules and sebacic anions. The water molecules and sebacic acid O atoms assembled 2D supramolecular corrugated sheets with different morphology in the two complexes. 相似文献

The saccharinato complexes [Zn(phen)2(sac)(H2O)]sac (1) and [Zn(sac)(dmp)(H2O)](sac) (2), where phen = 1,10-phenanthroline, dmp = 2,9-dimethyl-1,10-phenanthroline, and sac =saccharinato ion/ligand, were synthesized by the reaction of [Zn(sac)2(H2O)4] · 2H2O with ligands and have been characterized by elemental analysis, IR, and 1H NMR spectroscopies. Conductivity of complexes was measured in DMSO. Compound 1 is characterized by single crystal X-ray diffraction and compared with some isomorphous zinc-saccharinate complexes reported previously. Complex 1 crystallizes in the triclinic system, space group P 1 , with Z = 2, and consists of alternating slightly distorted octahedral [Zn(phen)2(sac)(H2O)]+ and noncoordinated saccharinate. The zinc bound aqua is hydrogen bonded to an oxygen of carbonyl in the saccharinate ligand and the SO2 group in the saccharinate counter-ion from an adjacent molecule. Intermolecular and intramolecular hydrogen bonds and C–H ··· O and C–H ··· N short contacts lead to a 3-D network. 相似文献

Substitution reactions take place following the photonic excitation of aqueous K4M(CN)8 (where M = Mo or W) in the presence of 1,10-phenanthroline and 2,2bipyridyl. Changes in absorbance with time show that the overall reaction is dependent on photochemical activation of potassium octacyanomolybdate(IV) and -tungstate(IV). The species [K2Mo(CN)4(OH)2(phen)], [K2W(CN)4(OH)2(phen)], [K2Mo(CN)4(OH)2(bipy)] and [K2W(CN)4(OH)2(bipy)] exist in solution. The final photosubstitution products [Mo(OH)3(CN)(phen)2] · 2H2O], [Mo(OH)3(CN)(bipy)2] · 3H2O, [W(OH)3(CN)(phen)2] · 2H2O and [W(OH)3(CN)(bipy)2] · H2O have been isolated in the solid state. Their IR spectra have been discussed. The quantum yield of the photosubstitution reactions has been determined and its variation with change of concentration of the complex as well as the H+ ion concentration has been studied. 相似文献

Reactions of a freshly prepared Zn(OH)2‐2x(CO3)x · yH2O precipitate, phenanthroline with azelaic and sebacic acid in CH3OH/H2O afforded [Zn(phen)(C9H15O4)2] ( 1 ) and [Zn2(phen)2(H2O)2(C10H16O4)2] · 3H2O ( 2 ), respectively. They were structurally characterized by X‐ray diffraction methods. Compound 1 consists of complex molecules [Zn(phen)(C9H15O4)2] in which the Zn atoms are tetrahedrally coordinated by two N atoms of one phen ligand and two O atoms of different monodentate hydrogen azelaato groups. Intermolecular C(alkyl)‐H···π interactions and the intermolecular C(aryl)‐H···O and O‐H···O hydrogen bonds are responsible for the supramolecular assembly of the [Zn(phen)(C9H15O4)2] complexes. Compound 2 is built up from crystal H2O molecules and the centrosymmetric binuclear [Zn2(phen)2(H2O)2(C10H16O4)2] complex, in which two [Zn(phen)(H2O)]2+ moieties are bridged by two sebacato ligands. Through the intermolecular C(alkyl)‐H···O hydrogen bonds and π‐π stacking interactions, the binuclear complex molecules are assembled into layers, between which the lattice H2O molecules are sandwiched.

The coordination compounds of group 12 halides with 2,2′-bipyridine (bpy) and 1,10-phenanthroline (phen), 2[CdF2(bpy)2]·7H2O (1), [ZnI(bpy)2]+·I3? (2), [CdI2(bpy)2] (3), [Cd(SiF6)H2O(phen)2]·[Cd(H2O)2(phen)2]2+·F–·0.5(SiF6)2–·9H2O (4), [Hg(phen)3]2+·(SiF6)2–·5H2O (5), [ZnBr2(phen)2] (6), 6[Zn(phen)3]2+·12Br–·26H2O (7) and [ZnI(phen)2]+·I– (8), have been synthesized and characterized by X-ray crystallography, IR spectroscopy, elemental and thermal analysis. Structural investigations revealed that metal?:?ligand stoichiometry in the inner coordination sphere is 1?:?2 or 1?:?3. A diversity of intra- and intermolecular interactions exists in structures of 1–8, including the rare halogen?halogen and halogen?π interactions. The thermal and spectroscopic properties were correlated with the molecular structures of 1–8. Structural review of all currently known coordination compounds of group 12 halides with bpy and phen is presented. 相似文献

Summary The electrochemical oxidation of anodic metals (nickel and cobalt) in MeCN solutions of 2-pyridinone (HOpy) or 2-pyridine
methanethiol-1-oxide (HPMTO) or its dimer, 2,2′-dithiodimethyldipyridine-1,1′-dioxide (DPMTO), gives the simple complexes
[Ni(Opy)2]·2H2O, [Co(Opy)2]·2H2O, [Ni(PMTO)2]·2H2O and [Co(PMTO)2]·3H2O. When 2,2′-bipyridine (bipy) or 1,10-phenanthroline (phen) was added to the electrolytic phase, only three mixed complexes
were obtained: [Ni(Opy)2bipy]·H2O, [Co·(Opy)2phen]·H2O and [Ni(Opy)2phen]·5H2O. The complexes were characterized by their elemental analyses, i.r. spectra and magnetic properties. 相似文献

Reactions of fresh M(OH)2 (M = Zn2+, Cd2+) precipitate and (RS)-2-methylglutaric acid (H2MGL), 2,2′-bipyridine (bipy), or 1,10-phenanthroline (phen) in aqueous solution at 50°C afforded four new metal–organic complexes [Zn2(bipy)2(H2O)2(MGL)2] (1), [Zn2(phen)2(H2O)(MGL)2] (2), [Cd(bipy)(H2O)(MGL)] · 3H2O (3), and [Cd(phen)(H2O)(MGL)] · 2H2O (4), which were characterized by single crystal X-ray diffraction, IR spectra, TG/DTA analysis as well as fluorescence spectra. In 1, the [Zn(bipy)(H2O)]2+ moieties are linked by R- and S-2-methylglutarate anions to build up the centrosymmetric dinuclear [Zn2(bipy)2(H2O)2(MGL)2] molecules. In 2, the 1-D ribbon-like chains [Zn2(phen)2(H2O)(MGL)2] n can be visualized as from centrosymmetric dinuclear [Zn2(phen)2(H2O)2(MGL)2] units sharing common aqua ligands. Both 3 and 4 exhibit 1-D chains resulting from [Cd(bipy)(H2O)]2+ and [Cd(phen)(H2O)]2+, respectively, bridged alternately by R- and S-2-methylglutarate anions in bis-chelating fashion. The intermolecular and interchain π···π stacking interactions form supramolecular assemblies in 1 and 1-D chains in 2–4 into 2-D layers. The hydrogen bonded lattice H2O molecules are sandwiched between 2-D layers in 3 and 4. Fluorescence spectra of 1–4 exhibit LLCT π → π* transitions. 相似文献

The self‐assembly reactions of transition metal ions and 1,3,5‐benzenetricarboxylic acid (H3btc) in the presence of auxiliary aromatic bidentate ligands 1,10‐phenanthroline (1,10‐phen) or 4,4′‐bipyridine‐N,N′‐dioxide (4,4′‐bpdo) have isolated four coordination polymers [Co18(btc)10(H2O)6(OH)6(1,10‐phen)6] · 14H2O · 3DMF ( 1 ) and [M3(btc)2(H2O)4(4,4′‐bpdo)] · 2H2O · 2DMF [M = Co ( 2 ), Mn ( 3 ), Ni ( 4 )]. Single‐crystal X‐ray diffraction analysis revealed that the M3 clusters in the structure of 1 – 4 are connected by hydroxyl group oxygen atoms (or oxygen atoms from 4,4′‐bpdo ligands) and carboxyl groups to generate a three‐dimensional framework. The network of final assemblies can be adjusted by varying the type of auxiliary ligands (1,10‐phen, 4,4′‐bpdo). In addition, the gas adsorption properties of 2 are also investigated. 相似文献

The title compound [La(phen)2(H2O)2(NO3)2](NO3) · 2(phen)(H2O) with phen = 1,10‐phenanthroline was prepared by the stoichiometric reaction of La(NO3)3 · 6 H2O and 1,10‐phenanthroline monohydrate in a CH3OH–H2O solution. The crystal structure (triclinic, P 1 (no. 2), a = 11.052(2), b = 13.420(2), c = 16.300(2) Å, α = 78.12(1)°, β = 88.77(1)°, γ = 83.03(1)°, Z = 2, R = 0.0488, wR2 = 0.1028) consists of [La(phen)2(H2O)2(NO3)2]2+ complex cations, NO3– anions, phen and H2O molecules. The La atom is 10‐fold coordinated by four N atoms of two bidentate chelating phen ligands and six O atoms of two H2O molecules and two bidentate chelating NO32– ligands with d(La–O) = 2.522–2.640 Å and d(La–N) = 2.689–2.738 Å. The intermolecular π‐π stacking interactions play an essential role in the formation of two different 2 D layers parallel to (001), which are formed by complex cations and uncoordinating phen molecules, respectively. The uncoordinated NO3– anions and H2O molecules are sandwiched between the cationic and phen layers. 相似文献

To explore the coordination possibilities of anthracene‐based ligands, three cadmium(ιι) complexes with anthracene‐9‐carboxylate ( L ) and relevant auxiliary chelating or bridging ligands were synthesized and characterized: Cd2( L )4(2bpy)2(μ‐H2O) ( 1 ), Cd2( L )4(phen)2(μ‐H2O) ( 2 ), and {[Cd3( L )6(4bpy)]}∞ ( 3 ) (2bpy = 2,2′‐bipyridine, phen = 1,10‐phenanthroline, and 4bpy = 4,4′‐bipyridine). Structural analyses show that complexes 1 and 2 both take dinuclear structures by incorporating the chelating 2bpy or phen ligand, which are further interlinked by intermolecular hydrogen‐bonding, π ··· π stacking, and/or C–H ··· π supramolecular interactions to generate higher‐dimensional supramolecular frameworks. Complex 3 has a one‐dimensional (1D) ribbon‐like structure, which is further assembled into a two‐dimensional (2D) layer, and a three‐dimensional (3D) framework by the co‐effects of interchain C–H ··· O hydrogen‐bonding and C–H ··· π supramolecular interactions. Moreover, the luminescent properties of these complexes were further investigated in detail. 相似文献
