Chlorido[N'-(2-oxidobenzil-idene)acetohydrazide-κO,N',O']copper(II) dihydrate

Abstract

In the title complex, [Cu(C(9)H(9)N(2)O(2))Cl]·2H(2)O, prepared from the Schiff base ligand N'-(2-hydroxy-benzil-idene)aceto-hydrazide and copper(II) chloride, the Cu(II) atom is coord-inated by two O atoms and one N atom from the ligand and by a Cl atom in a distorted square-planar geometry. The two donor O atoms of the tridentate Schiff base ligand are in a trans arrangement. In the crystal structure, there is an extensive inter-molecular hydrogen-bonding network; N-H⋯O, O-H⋯O and O-H⋯Cl inter-actions, involving the uncoordinated water mol-ecules, lead to the formation of a two-dimensional network parallel to the ab plane.
