Chloridobis[2-(1,5-dimethyl-1H-pyrazol-3-yl-κN2)-1-methyl-1H-imidazole-κN3]copper(II) chloride methanol hemisolvate tetrahydrate

Abstract

In the title compound, [CuCl(C9H12N4)2]Cl·0.5CH3OH·4H2O, the CuII ion adopts a distorted trigonal-bipyramidal coordination arising from two bidentate ligands and a Cl− anion. The two heterocyclic ligands are planar with dihedral angles of 3.4 (1) and 0.7 (1)° between the pyrazole and imidazole rings. In the crystal, water molecules and uncoordinated chloride anions form an O—H...Cl and O—H...O hydrogen-bonded sheet parallel to (100) which lies between two layers of complex molecules. The packing is further stabilized by C—H...Cl and C—H...O hydrogen bonds. The methanol solvent molecule is disordered across a centre of inversion.
