biostudies-literatureUnknown67(Pt 12)Datta AIn the title compound, [CuCl(2)(C(8)H(9)N(3)O)], the Cu(II) atom has a distorted square-pyramidal CuCl(2)N(2)O 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. Inter-molecular N-H⋯Cl hydrogen bonds are present in the crystal, leading to the formation of chains along [10[Formula: see text]].Acta crystallographica.
