摘　　要：有机-无机杂化材料因其在催化、化学吸附、磁性和电子导体等方面具有广泛的应用而成为人们的研究热点。通过过渡金属离子和特殊的有机配体之间的反应,一系列具有独特结构的配位聚合物已被合成出来。多齿有机配体可螯合两个或多个金属离子,这些金属离子之间存在良好的电子交换,可形成一维、二维或三维的配位聚合物。A novel 3-D coordination polymer, [Cu3(μ10-bta) (μ2C2O4) (H2O)2],(bta = benzene-1,2,4,5-tetracarboxylate) , was hydrothermally synthesized from CuMoO4, H4bta (H4bta = benzene-1, 2, 4, 5-tetracarboxylic acid) , H2C2O4, NaOH and H2O, and characterized by elemental analysis, IR spectrum and X-ray crystallography. The crystals of the compound belong to orthorhombic space group Pbcn, a = 0. 710 17(14) nm, 6=1. 257 7(3) nm, γ=l. 597 2(3) nm, V = l. 426 6(5) nm3. Z = 4, Dc = 2. 6309g/cm3, μ=4. 525 mm-1, F(000) = l 108, GOF = 1.054, ρmax= 1 082 e/nm3, ρmin = - 608 e/nm3, R=0. 038 1, RW = 0. 130 7. The coordination environment of Cu(2)2+ is a seriously distorted octahedron, while that of Cu(1)2+ is a highly symmetric octahedron. In the compound, each bta4- lig-and displays an unprecedented μ10-coordination mode, whereas C2O2-4 ligand shows a μ2coordination form. There are three-dimensional interpenetrated channels in the solid of the compound.
