Abstract
A phthalate-bridged copper(II) complex {[Cu(phth)(Phen)(H2O)] ⋅ H2O} n (H2phth: 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) Å, b = 11.1709(3) Å, c = 14.0532(4) Å, V = 1831.28(9) Å3, Z = 4. The L2− (the acid radical of H2phth) 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.
