Abstract
A novel copper(II) complex {[Cu(BIX)2(H2O)2](PhCOO)2}n (1) (BIX = 1,4-bis(imidazole-1-methyl))benzene) is synthesized and characterized by elemental analysis, IR, TG, and single crystal X-ray diffraction. Complex 1 crystallizes in the triclinic crystal system with the P-1 space group, Z = 1, a = 9.465(2) Å, b = 9.703(2) Å, c = 12.060(2) Å, α = 77.26(3), β = 70.37(3), γ = 67.14(3)°, and V = 956.1(3) Å3. The crystal structural analysis of complex 1 shows that the copper center is six-coordinated in an elongated octahedral geometry by four N atoms from four different BIX and two O atoms from two water molecules; two neighboring Cu(II) cations are bridged by two BIX extending into an infinite 1D double chain structure.
