摘要
A one-dimensional chain coordination polymer [Cu(phen)(2,4,6-TMBA)2(H2O)]n has been synthesized by reacting 2,4,6-trimethyl-benzoic acid, 1,10-phenanthroline and Cu(II) per- chlorate and its structure was characterized. Crystal data for this complex: tetragonal, space group I41, a = 2.0293(3), b = 2.0293(3), c = 1.3758(2) nm, α = β = γ = 90°, V = 5.6657(13) nm3, Dc = 1.379 g/cm3, Z = 8, μ(MoKα) = 0.815 mm?1, Mr = 588.14, F(000) = 2456, S = 1.047, R = 0.0459 and wR = 0.1053. The crystal structure shows that two neighboring Cu(Ⅱ) ions are linked together by one bridging-chelating 2,4,6-trimethyl-benzoic group, forming a one-dimensional chain structure. Each Cu(Ⅱ) ion is coordinated with two nitrogen atoms from one 1,10-phenanthroline molecule, three oxygen atoms from three 2,4,6-trimethyl-benzoic acid molecules and one oxygen atom from one water molecule, giving a six-coordinate distorted octahedral coordination geometry. The cyclic voltammetry behavior of the complex was also investigated.
