Dichlorotetrakis(4-methylimidazole)copper(II)

C. Näther, M. Wriedt and I. Jeß

Abstract: In the structure of the title compound, [CuCl₂(C₄H₆N₂)₄], the copper(II) cation is surrounded by four 4-methylimidazole ligands within a slightly distorted square plane. The coordination sphere is completed by two contacts to Cl atoms which are elongated due to the Jahn-Teller distortion. The coordination polyhedron around the copper(II) cations can be described as a strongly distorted octahedron. The copper(II) cations are located on centres of inversion, whereas the two crystallographically independent 4-methylimidazole ligands and the chloride anion occupy general positions. There are short N-HCl distances to the Cl atoms indicating hydrogen bonding.
