Abstract

The title compound, [Cu(2)(C(15)H(11)BrN(2)O(4))(2)(C(3)H(7)NO)(2)], is derived from the reaction of N'-(5-bromo-2-hy-droxy-3-meth-oxy-benzyl-idene)-2-hy-droxy-benzohydrazide and copper nitrate in a dimethyl-formamide solution in the presence of sodium hydroxide. The compound can be regarded as a binuclear centrosymmetric complex. In the crystal, the Cu(II) atom is fivefold surrounded and adopts a distorted square-pyramidal coordination environment. An intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecular conformation.
