By aging a mixture of ammonia solution of copper acetate and of 2-ethylimidazole in ethanol, crystals of the copper acetate-2-ethylimidazole complex were obtained. The solid crystallizes in the monoclinic P21/n space group with two formula units per unit cell. In the structure the copper atom is found in distorted square-planar coordination to three oxygen atoms from acetate groups and to the N atom of a 2-ethylimidazole molecule. To the solid stability and the complex configuration, a network of hydrogen bonding interactions is contributing. Both the ethyl and NH groups of 2-ethylimidazole were found forming hydrogen bridges with the oxygen atoms of the acetate groups. The structural information derived from X-ray single-crystal analysis was complemented with infrared and thermogravimetric data. Copyright © Taylor & Francis Group, LLC 2015.
