Abstract

Abstract: Anovel 3-Dcoordination 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. 71017(14) nm, 6=1. 2577(3) nm, γ=l. 5972(3) nm, V=l. 4266(5) nm³. Z=4, D_c= 2. 6309g/cm³, μ=4. 525 mm^-1, F(000)=l 108, GOF=1.054, Δρ_max= 1082 e/nm³, Δρ_min= - 608 e/nm³, R=0. 0381, R_W= 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 bta^4-lig-and displays an unprecedented μ₁₀-coordination mode, whereas C₂O₄^2-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
