Chlorido[N′-(2-oxidobenzilidene)acetohydrazide-κ²O,N′,O′]copper(II) dihydrate

Abstract

In the title complex, [Cu(C9H9N2O2)Cl]·2H2O, prepared from the Schiff base ligand N′-(2-hydroxy­benzil­idene)aceto­hydrazide and copper(II) chloride, the CuII atom is coord­inated 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 inter­molecular hydrogen-bonding network; N—H⋯O, O—H⋯O and O—H⋯Cl inter­actions, involving the uncoordinated water mol­ecules, lead to the formation of a two-dimensional network parallel to the ab plane.
