Bis{(E)-2-[2-(2-hydroxybenzoyl)hydrazono]propanoato-κ3O,N,O′}copper(II) trihydrate

Abstract

The title compound, [Cu(C10H9N2O4)2]·3H2O, was obtained by evaporation of an aqueous ethanol solution of 2-[2-(2-hydroxy­benzo­yl)hydrazono]propanoic acid and cupric chloride. Each CuII atom is six-coordinated in a distorted octa­hedral geometry by carboxylate and acyl O atoms and imide N atoms from two tridentate ligands in the keto form, forming two five-membered rings sharing one edge for each ligand. N—H⋯O and O—H⋯O hydrogen bonds between water mol­ecules and the ligands result in the formation of a three-dimensional network.
