[N-(2-Hydroxy-ethyl)ethyl-enediamine]oxalatocopper(II)

Abstract

In the title mononuclear copper(II) compound, [Cu(C<inf>2</inf>O <inf>4</inf>)(C<inf>4</inf>H<inf>12</inf>N<inf>2</inf>O)], the CuII ion has a slightly distorted square-pyramidal geometry, with a tridentate N-(2-hydroxy-ethyl)ethyl-enediamine (HydEt-en) and a bidentate oxalate (ox) ligand. The N atoms of the HydEt-en ligand and the O atoms of ox ligand form the basal plane, while the O atom of the ethanol group of the HydEt-en ligand is located in the axial position. The complex mol-ecules participate in a supra-molecular assembly through N- H⋯O and O- H⋯O hydrogen bonds between HydEt-en and ox ligands.
