Dichlorido{N′-[(pyridin-2-yl)methylidene-κN]acetohydrazide-κ2N′,O}copper(II)

Abstract

In the title compound, [CuCl2(C8H9N3O)], the CuII atom has a distorted square-pyramidal CuCl2N2O coordination geometry. The tridentate acetohydrazide ligand occupies three basal positions, the fourth basal position being defined by a chloride anion at a distance of 2.2116 (6) Å. The second chloride anion is in the apical position and forms a longer Cu—Cl distance of 2.4655 (7) Å. Intermolecular N—H...Cl hydrogen bonds are present in the crystal, leading to the formation of chains along [10overline{1}].
