摘要
The cadmium(II) complex [Cd(phba)(2)(bim)(H2O)(2)](n) (1) (phba = 4-hydroxybenzoate, bim = 1,2-bis(imidazol-1-yl)ethane) has been synthesized and structurally characterized by X-ray diffraction analysis. It crystallizes in the monoclinic space group C2/c, a = 23.820(4) angstrom, b = 9.5331(14) angstrom, c = 11.1086(19) angstrom, beta = 111.519(4)degrees, V = 2346.7(7) angstrom(3), Z = 4. The coordination geometry of Cd(II) atom is distorted octahedral; it is coordinated by two nitrogen atoms from the imidazole rings of two symmetry-related bim molecules, and four oxygen atoms from two symmetry-related phba anions and two water molecules. The Cd(II) atoms are bridged by bim molecules to form a one-dimensional chain.
