Abstract

The crystal and molecular structure of the monomeric title compound, chlorotetrakis(2-methylimidazole)copper(II) chloride, [CuCl(C4H 6N2)4]Cl, is presented, and compared with those of two other closely related monomeric structures. The monomers are similar, but the supramolecular structures are very different. The influence that steric effects might have in determining crystal properties, such as space group symmetry or packing efficiency, is analysed. © 2003 International Union of Crystallography Printed in Great Britain - all rights reserved.
