A new Cu(II) complex [Cu(HPht)2(1-CH3Im) 2] (I), where HPht is the monoanion of o-phthalic acid and 1-CH 3Im is 1-methylimidazole, is synthesized and characterized by IR spectroscopy, thermogravimetry, and X-ray diffraction analysis. Compound I contains molecular complexes in which the o-phthalic acid residue is monodeprotonated and linked to a metal through the carboxyl group in a 1,3-chelate mode. The cis-octahedral coordination of copper is formed by two HPht residues and two 1-CH3Im molecules. The distances are Cu-N1.945(6) Å, Cu-O2.018(5) Å and 2.374(6) ̊. Polymeric chains are formed in complex I due to intermolecular O-H⋯O hydrogen bonds. The chains are unified into layers by the C -H·π interactions between the 1-CH3Im molecules of the adjacent complexes |
