title: Dichlorido{N'-[1-(2-pyridin-2-yl)ethyl-idene]acetohydrazide-κN',O}copper(II).
abstract: In the title compound, [CuCl(2)(C(9)H(11)N(3)O)], the Cu(II) atom is in a distorted square-pyramidal CuCl(2)N(2)O coordination geometry. The tridentate acetohydrazide ligand chelates in a meridional fashion. The chloride ligand in the axial position forms a long Cu-Cl distance of 2.4892 (9) Å. In contrast, the Cu-Cl distance from the equatorial chloride ligand is much shorter [2.2110 (7) Å]. Inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds link the complexes into a three-dimensional network.
