The title complex, [Co_2(bpdc)_2(bim)_4]_n(bpdc=biphenyl-2,2′-dicarboxylate dianion, bim=benzimidazole), was synthesized in a aqueous solution and its crystal structure was determined by means of X-ray diffraction. There are two different coordinated Co(Ⅱ) centers in the complex. The Co1 center has a deformed trigonal-bipyramidal geometry, while the Co2 center possesses a tetrahedral geometry. In addition, the two different coordination modes of bpdc ligands act as two kinds of bridges to link Co1 and Co2, resulting in a catena chain. 展开更多

A new dimeric compound, [Zn(bpdc)(L)]2·4H2O(1, L = 11-fluoro-dipyrido[3,2-a:2',3'-c]phenazine and bpdc = 1,1'-biphenyl-2,2'-dicarboxylate), has been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction. It crystallizes in monoclinic, space group C2/c with a = 23.671(5), b = 22.547(5), c = 13.741(3)A, β = 123.47(3)°, V = 6118(2) A3, Z = 4, C66H44Cl2F2N8O12Zn2, Mr = 1380.73, Dc = 1.499 g/cm3, F(000) = 2816, μ(MoKa) = 0.949 mm-1, R = 0.0572 and wR = 0.1620. In 1, Zn1 and the symmetry formed Zn1 ions are connected by four bridging bidentate carboxylate groups from two independent bpdc anions to yield a binuclear unit with the Zn···Zn separation by bpdc anions of 4.168. Two L ligands are located on both sides of the dimer in chelating bidentate modes. The lateral L ligands from neighboring dimers are paired through strong π-π interactions to result in a fascinating 1D ladder-like supramolecular array. In addition, neighboring supramolecular ladders are packed each other to yield a 3D supramolecular architecture with a 1D channel. 展开更多

The coordination polymer [Zn1.5(2,2?,4??-tpt)(tpa)2]n (2,2?,4??-tpt = 3,4-bis(2- pyridyl)-5-(4-pyridyl)-1,2,4-triazole, H2tpa = terephthalic acid) has been obtained by solution evaporation method and characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction. The title compound crystallizes in the triclinic system, space group P , with a = 10.331(3), b = 10.596(1), c = 14.966(3) ?, β = 99.029(0)o, V = 1448.86(6) ?3, Z = 2, Dc = 1.668 g/cm3, μ = 1.320 mm-1, F(000) = 740, R = 0.0359 and wR = 0.0841 with I 〉 2σ(I)). In this polymer, the asymmetric unit contains two crystallographically independent Zn(II) ions in different coordination environments. Zn(1) ion is five-coordinated, forming a distorted tetragonal pyramidal geometry, while the Zn(2) ion is six-coordinated to get a distorted octahedral geometry. Each Zn(II) ion is linked by 2,2?,4??-tpt and H2tpa ligands, forming an infinite 2D structure. The existence of O(8)–H(8)???O(2) hydrogen bonding interactions leads the 2D chains to generate a 3D structure. In addition, 1 shows strong photoluminescent emissions in the solid state at room temperature, so it can be used as potential optical materials. 展开更多
