A novel water cluster [Mn(phen)2·H2O·Cl]·p-FBA·3H2O (p-FBA = p-fluorobenzoic acid and phen = 1,10-phenanthroline) was synthesized by the hydrothermal reaction of MnCl2 with p-FBA and phen at 150 ℃ and characterized by elemental analysis,IR spectra and TG. Its crystal structure was determined by X-ray single-crystal diffraction study. The crystal belongs to the triclinic system,space group P1,with a = 10.5768(1),b = 11.5960(1),c = 12.9916(2) ,α = 101.816(2),β = 95.397(2),γ = 103.052(2)o,V = 1502.8(3) 3,Z = 2,Dc = 1.463 g/cm3,R = 0.0399 and wR = 0.0997. The crystal structure shows that the manganese(Ⅱ ) ion is six-coordinated by four nitrogen atoms,one chloride ion and one oxygen atom forming a distorted octahedral coordination geometry. The structure includes three acyclically connected water molecules and one coordinated water molecule thus forming a (H2O)4 water cluster. This water pattern forms a cross-linked discrete ring. The steady (H2O)4 is further extended into a cage-like structure by the hydrogen-bonding interaction formed by dissociative aqua molecule and Cl-ligand. The dimer structure is further extended into a one-dimensional (1D) structure through C-H···O interaction. π···π Stacking interaction among adjacent phen aromatic rings further stabilizes the crystal structure.  相似文献

Each MoV atom has a distorted octahedral coordination geometry,and the two coordination octahedra share a common edge to form a dioxo-bridged Mo2O4 unit which is coordinated by NTA ligands. The dianionic binuclear units [Mo2O4(HNTA)2]^2- are interconnected by Na^+ into a layered structure.  相似文献

1 INTRODUCTION In the last decade, there has been great interest in the crystal engineering of supramolecular architectures organized by coordinate covalent bonds, hydrogen bonds and their combination owing to their fascinating structural diversity and potential applications as functional materials[1~3]. The self-assembly of coordinate polymers and supramolecules is highly influenced by factors such as ligands, metal ions, the counter ions, solvent, template, reaction temperature, pH va…  相似文献

The title complex [Cu2(Sams)2(H2O)2(bipy)]·(H2O) 1 (H2Sams = N-(2-hydroxybenzy) aminomethanesulfonic acid, bipy = 4,4′-bipyridine) has been synthesized by the reaction of Cu- (CH3COO)2·H2O, nESams and 4,4′-bipyridine in aqueous methanol. It was characterized by IR, elemental analysis, thermogravimetric analysis (TGA) and X-ray diffraction analysis. Complex 1 crystallizes in monoclinic, space group P21/n with a= 10.9533(17), b = 8.3408(13), c = 16.714(3) A^°, β = 101.295(4)°, V = 1494.3(4) A^°3 and Z = 2. The asymmetric unit is comprised of a tridentate Schiff base Sams^2- anionic ligand, a 4,4′-bipyddine and two coordinated water molecules, thus forming a binuclear copper(Ⅱ) complex. The coordination environment at Cu^Ⅱ center is described as a slightly distorted square pyramidal geometry. Via intermolecular hydrogen bonds C(10)-H(10)…O(3) and C(13)- H(13)…O(3), an infinite supramolecular chain is yielded. A number of intermolecular hydrogen bonds greatly contribute to the stabilization of the solid-state structure for 1.  相似文献

A novel coordination polymer of [Zn(4-CPOA)(Phen)(H2O)]n (C21H16N2O6Zn,1,4-CPOA = 4-carboxylato-phenoxyacetate dianion and Phen = 1,10-phenanthroline) has been synthesized and characterized by elemental analysis,IR,TG,PL and single-crystal X-ray diffraction. The crystal crystallizes in the triclinic system,space group of P1 with a = 9.622(3),b = 9.631(3),c = 11.526(4)A,α = 67.719(5),β = 71.203(5),γ = 83.552(6)o,V = 935.5(5) A^3,Z = 2,Dc = 1.625 g/cm^3,μ = 1.357 mm^-1 and F(000) = 468. The Zn(II) ion is surrounded by three carboxylate O atoms from two different 4-CPOA groups,two N atoms from the Phen ligand and one water molecule,forming a distorted octahedral coordination configuration. The Zn(II) ions were alternately interlinked by carboxylate groups of 4-CPOA with chelating bisbidentate and monodentate modes into a one-dimensional zigzag chain having an intrachain distance of ca. 9.631(1) . Under the direction of supramolecular recognition and attraction,the adjacent chains yield a double-stranded chain through π-π stacking between the phen ligands,which was further expanded into a 2-D framework via strong C–H–π interaction (ca. 2.95(1) ) between the 4-CPOA ligands and into a 3-D supramolecular network by strong hydrogen bond between terminal water molecule and carboxyl group. TG/DTG shows that its chain skeleton is thermally stable up to 419 oC and the blue fluorescent emission of the complex was determined at 471 nm in a solid state with its long decay lifetime of 1.83 ns.  相似文献
