摘要

A phthalate-bridged copper(II) complex {[Cu( phth)(Phen)(H2O)] center dot H2O}(n) (H(2)phth: phthalic acid, Phen: 1,10-phenanthroline) has been synthesized by the reaction of CuCl2 and phthalic acid in the presence of 1,10-phenanthroline in aqueous solution. The crystal structure of the complex has been determined by X-ray diffraction analysis to be orthorhombic, with the centrosymmetric space group Pbcm, where a = 11.6652( 3) angstrom, b = 11.1709( 3) angstrom, c = 14.0532( 4) angstrom, V = 1831.28( 9) angstrom(3), Z = 4. The L2- (the acid radical of H(2)phth) ion is coordinated to the Cu2+ ion as a monodentate ligand. Each L2- ion bridges two adjacent Cu2+ ions with its two oxygen atoms from two carboxylic groups to form a one-dimensional zigzag chain. The coordination water and uncoordinated carboxylic oxygen atoms from neighboring chains are linked through hydrogen bonds to form a two-dimensional structure. There is a weak interaction between the coordination water molecule and the Cu2+ ion in the neighboring chain.
