Abstract: Anovel 3-Dcoordination polymer, [Cu310-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. 71017(14) nm, 6=1. 2577(3) nm, γ=l. 5972(3) nm, V=l. 4266(5) nm3. Z=4, Dc= 2. 6309g/cm3, μ=4. 525 mm-1, F(000)=l 108, GOF=1.054, Δρmax= 1082 e/nm3, Δρmin= - 608 e/nm3, R=0. 0381, RW= 0. 1307. 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 C2O42-ligand shows a μ2coordination form. There are three-dimensional interpenetrated channels in the solid of the compound.

Key words: Hydrothermal synthesis, Crystal structure, Benzene-1, 2, 4, 5-tetracarboxylate, Coordinated polymer
