Di-μ-acetato-κ4O:O-bis{2-[(2-aminoethyl)iminomethyl]phenolato-κ3N,N′,O}copper(II)

Abstract

The title complex, [Cu2(C9H11N2O)2(C2H3O2)2] or Cu2L2OAc2 [L is (salicylideneimino)ethyl­amine and OAc is acetate], has a centrosymmetric acetate-bridged dinuclear structure with each CuII ion in a distorted square-pyramidal coordination geometry, the angles at the CuII ion deviating from ideal values. The basal plane is occupied by two N atoms, one phen­oxy O atom and one O atom from an OAc ligand, with an O atom of a bridging OAc ligand in the apical position. The apical Cu—O bond distance is longer than the equatorial Cu—N or Cu—O bond distances. In the crystal structure, inter­molecular hydrogen bonds involving the amino N atom and the uncoordinated acetate ligand O atom connect the dinuclear units into a two-dimensional network.
