Two novel interdigitated metal‐quinolone complexes, namely [Cu2(cfH)2(bptc)(H2O)] · 4H2O ( 1 ) and [Zn2(levofH)2(odpa)] · 5.5H2O ( 2 ) (bptc = 3,3′,4,4′‐benzophenonetetracarboxylate, cfH = ciprofloxacin, odpa = 4,4′‐oxydiphthalate, levofH = levofloxacin) were synthesized hydrothermally and characterized by elemental analyses, IR spectra, UV/Vis spectra, TG analyses, powder X‐ray diffraction, and single‐crystal X‐ray diffraction. Moreover, solid‐state photoluminescence property of compound 2 was also investigated at room temperature. Compound 1 exhibits a novel interdigitated architecture, which is built from 1D chains with side arms. The structure of compound 2 consists of 1D chains with dangling levofloxacin ligands protruding from both sides of the chain, and these chains are interdigitated with each other to generate a interdigitated framework. 相似文献

The mononuclear compounds [Cu(OAc)(bipy)2]Cl·4H2O·1/2MeOH( 1 ) and [Co(OH2)2(phen)2](OAc)2·6H2O( 2 ) were unexpectedly obtained as single crystals from mother liquors left following isolation of the expected products of the reactions, in ethanol of Cu(OAc)2, benzylic acid and 2, 2'‐bipyridine (for 1 ) and Co(OAc)2, D, L‐mandelic acid and 1, 10‐phenanthroline (for 2 ). The complexes were characterized by elemental analysis, IR and electronic spectroscopy and magnetic measurements at room temperature and their structures were determined by single‐crystal X‐ray analysis. In 1 , the pentacoordinated copper atom has a basically square pyramidal coordination polyhedron, while in 2 the cobalt atom has a distorted octahedral environment. In both cases, the complexes are linked by hydrogen bonds and aromatic‐aromatic interactions. 相似文献

Two sulfato CuII complexes [Cu2(bpy)2(H2O)(OH)2(SO4)]· 4H2O ( 1 ) and [Cu(bpy)(H2O)2]SO4 ( 2 ) were synthesized and structurally characterized by single crystal X—ray diffraction. Complex 1 consists of the asymmetric dinuclear [Cu2(bpy)2(H2O)(OH)2(SO4)] complex molecules and hydrogen bonded H2O molecules. Within the dinuclear molecules, the Cu atoms are in square pyramidal geometries, where the equatorial sites are occupied by two N atoms of one bpy ligand and two O atoms of different μ2—OH groups and the apical position by one aqua ligand or one sulfato group. Through intermolecular O—H···O and C—H···O hydrogen bonds and intermolecular π—π stacking interactions, the dinuclear complex molecules are assembled into layers, between which the hydrogen bonded H2O molecules are located. The Cu atoms in 2 are octahedrally coordinated by two N atoms of one bpy ligand and four O atoms of two H2O molecules and two sulfato groups with the sulfato O atoms at the trans positions and are bridged by sulfato groups into 1[Cu(bpy)(H2O)2(SO4)2/2] chains. Through the interchain π—π stacking interactions and interchain C—H···O hydrogen bonds, the resulting chains are assembled into bi—chains, which are further interlinked into layers by O—H···O hydrogen bonds between adjacent bichains. 相似文献

Coordination Polymeric 1, 2‐Dithiooxalato and 1, 2‐Dithiosquarato Complexes. Syntheses and Structures of [BaCr2(bipy)2(1, 2‐dtox)4(H2O)2], [Ni(cyclam)(1, 2‐dtsq)]·2DMF, [Ni(cyclam)Mn(1, 2‐dtsq)2(H2O)2]·2H22, and [H3O][H5O2][Cu(cyclam)]3[Cu2(1, 2‐dtsq)3]2 1, 2‐Dithioxalate and 1, 2‐dithiosquarate ions have a pair of soft and hard donor centers and thus are suited for the formation of coordination polymeric complexes containing soft and hard metal ions. The structures of four compounds with building blocks containing these ligands are reported: In [BaCr2(bipy)2(1, 2‐dtox)4(H2O)2] Barium ions and pairs of Cr(bipy)(1, 2‐dtox)2 complexes form linear chains by the bisbidentate coordination of the dithiooxalate ligands towards Ba2+ and Cr3+. In [Ni(cyclam)(1, 2‐dtsq)]·2DMF short NÖH···O hydrogen bonds link the NiS2N4‐octahedra with C2v‐symmetry to an infinite chain. In [Ni(cyclam)Mn(1, 2‐dtsq)2(H2O)2]·2H2O the 1, 2‐dithiosquarato ligand shows a rare example of S‐coordination towards manganese(II). The sulfur atoms of cis‐MnO2S4‐polyedra are weakly coordinated towards the axial sites of square‐planar NiN4‐centers, thus forming a zig‐zag‐chain of Mn···Ni···Mn···Ni polyhedra. [H3O][H5O2][Cu (cyclam)]3[Cu2(1, 2‐dtsq)3]2 contains square planar [CuII(cyclam)]2+ ions and dinuclear [CuI2(1, 2‐dtsq)3]4— ions. Here each copper atom is trigonally planar coordinated by S‐donor atoms of the ligands. The Cu…Cu distance is 2.861(4)Å. 相似文献

Six new thioantimonates(III) with the [Sb4S7]2− anion were obtained under solvothermal conditions with in‐situ formed transition metal complexes as structure directors. In the two isostructural compounds [Fe(dien)2]Sb4S7·H2O ( 1 ) and [Co(dien)2]Sb4S7·0.5 H2O ( 2 ) (dien = diethylenetriamine; space group: P21/c) the layered [Sb4S7]2− anion is characterized by Sb8S8 rings with a diameter of about 9.6·7.6Å. The cation complexes are located above and below the pores of the rings. Despite the larger size of the cation complex the network topology of the third thioantimonate [Ni(dien)(tren)]Sb4S7 ( 3 ) (tren = tris(2‐aminoethyl)amine; space group: P21/n) is similar to that of the first two compounds. In the isostructural thioantimonates [M(trien)]Sb4S7 (M = Zn ( 4 ); M = Mn ( 5 ); trien = triethylenetetramine; space group: ) the M2+ ions are fivefold coordinated by four N atoms of the amine molecule and by one S atom of the thioantimonate anion forming a MN4S trigonal bipyramid. Sb8S16 building blocks are the central structural motifs of the anion. Two of the terminal S atoms at the periphery of the Sb8S16 units are bound to M2+ ions and the four remaining terminal S atoms connect adjacent Sb8S16 groups into the final [Sb4S7]2− chain. [Ni(tren)]Sb4S7 ( 6 ) (space group: ) contains a one‐dimensional anionic chain. The Ni2+ ion has two bonds to the [Sb4S7]2− anion which is a unique feature in the thioantimonate(III) chemistry. The NiN4S2 octahedron is severly distorted with one very long Ni‐S bond of 2.782(2) Å. In all compounds several short S···H distances indicate hydrogen bonding interactions. 相似文献

[Hg(sulfamethoxazolato)2]·2DMSO ( 1 ) and [Cu2(CH3COO)4(sulfa‐methoxazole)2] ( 2 ) can be obtained by the reaction of sulfamethoxazole with mercury acetate or copper acetate in methanol. The structures of the two complexes were characterized by single crystal X—ray diffractometry. Compound 1 consists of sulfamethoxazolato ligands bridging the metal ions building an unidimensional chain. Two solvent dimethylsulfoxide molecules are involved via N‐H···O hydrogen bridges. The mercury atom shows a linear primary coordination arrangement formed by two trans deprotonated sulfonamidic nitrogen atoms. The overall coordination around the metal atom may be regarded as a strongly distorted octahedron when the interactions of mercury with four sulfonamidic oxygen atoms [bond distances of 2.761(4) Å—2.971(4) Å] are also considered to build an equatorial plane and the N1 and N1′ atoms [bond distance of 2.037(5) Å] occupy the apical positions. Compound 2 is a dinuclear complex in which the copper ions are bridged by four syn‐syn acetate ligands which are related by a symmetry centre located in the centre of the complex. Each copper atom presents a nearly octahedral coordination where the equatorial plane is formed by four oxygen atoms and an isoxazolic nitrogen atom and the second copper atom occupy the apical positions. 相似文献

The reaction of copper(I) chloride with 6‐aza‐2‐thiothymine (ATT, 1 ) and triphenylphosphane in methanol/chloroform gives [(ATT)CuCl(PPh3)] ( 2 ) as a neutral complex. [(ATT)Ag(NO3)(PPh3)2]·MeOH ( 3 ) can be obtained by the reaction of 1 with silver(I) nitrate and triphenylphosphane in methanol/chloroform in excellent yields and the single crystals of 3 can be obtained from acetonitril solution. Both complexes were characterized by infrared spectroscopy, elemental analyses as well as by X‐ray diffraction studies.

Two novel lanthanide complexes with the formula [Er4(tp)6(H2O)6] ( 1 ) and [Lu(tp)1.5(H2O)3] ( 2 ) (tp = terephthalate) were synthesized by treating Er(NO3)3, Lu(NO3)3 with terephthalic acid under hydrothermal conditions, respectively. The structures were determined by X‐ray crystallography. The crystal 1 is of orthorhombic, space group Pbca(61) with a = 9.6656(2) Å, b = 26.2338(5) Å, c = 37.9022(7) Å, C48H36Er4O30, M = 1761.81, Z = 8, V = 9610.69(32) Å3, F(000) = 6688, R1 = 0.0326 and ωR = 0.0650. The crystal of 2 is of triclinic, space group with a = 7.8204(1) Å, b = 9.5355(1) Å, c = 10.6348(1) Å, α = 68.869(1)°, β = 71.081(1)°, γ = 75.151(1)°, C24H24Lu2O18, M = 475.19, Z = 2, V = 690.98(1) Å3, F(000) = 454, R1 = 0.0215 and ωR = 0.0474.

Reactions of freshly prepared Cu(OH)2—2x(CO3)x · yH2O and imidazole (Imid) with succinic acid and fumaric acid, respectively, in CH3OH/H2O yields Cu(Imid)2(H2O)L with L = (C4H4O4)2— ( 1 ) and (C4H2O4)2— ( 2 ). Both isostructural complexes consist of 1D [Cu(Imid)2(H2O)L2/2] polymeric chains, in which the T‐shaped [Cu(Imid)2(H2O)]2+ moieties are bridged by bis‐monodentate dicarboxylato ligands. Through the interchain hydrogen bonds between the coordinating H2O molecule and the non‐coordinating carboxylate O atom, the polymeric chains are assembled into 2D layers, which are further assembled via interlayer N—H···O hydrogen bonds between imidazole N atom and the coordinating carboxylato O atom. Thermal analyses of 1 under N2 stream showed that dehydration is immediately followed by decomposition of the anhydrous “Cu(Imid)2(C4H4O4)” intermediate into imidazole and “Cu(C4H4O4)”. Upon further heating, sublimation of imidazole is followed by dissociation of the resulting “Cu(C4H4O4)” into CO, CO2, C2H4 in gaseous phase and solid CuO as residue. Crystal data: ( 1 ) C2/c (no. 15), a = 13.712(2), b = 5.589(1), c = 17.517(2)Å, β = 105.76(1)°, U = 1292.0(3)Å3, Z = 4; ( 2 ) C2/c (no. 15), a = 13.758(2), b = 5.501(1), c = 17.464(2)Å, β = 106.05(2)°, U = 1270.2(3)Å3, Z = 4. 相似文献

Two nitrilotriacetate cobalt complexes {[CoK2(NTA)(Hmta)(H2O)3]NO3}n ( 1 ) and [{Co(4,4′‐bpy)2(H2O)4}{Co2(NTA)2(4,4′‐bpy)(H2O)2}] ( 2 ) (NTA = nitrilotriacetate anion, Hmta = hexamethylenetetramine and 4,4′‐bpy = 4,4′‐bipyridine) were prepared and characterized by IR, elemental analysis and single crystal X‐ray diffraction study. The influence of the neutral ancillary ligands on the formation of the complexes with different structures in the Co‐NTA system was discussed. The coordination of NTA and Hmta to Co2+ ions only resulted in the formation of mononuclear [Co(NTA)(Hmta)]? ions which are further connected by K+ ions and water molecules to form a three‐dimensional network. The use of 4,4′‐bpy as ancillary ligand in 2 led to the formation of separate mononuclear [Co(4,4′‐bpy)2(H2O)4]2+ and dinuclear [Co2(NTA)2(4,4′‐bpy)(H2O)2]2? which are further connected by hydrogen bonds to form a supramolecular three‐dimensional network. In these cases it seems to suggest that the addition of neutral ancillary ligand into the Co‐NTA system leads to the formation of lower dimensional structures when the contribution of alkali ions to the structural dimensionality is neglected. 相似文献
