[N-(2-Hydroxyethyl)ethylenediamine-κ3N,N',O]-cis-Bis(isothiocyanato-κN)copper(II)

Abstract

In the novel transition metal isothiocyanate complex of N-(2-hydroxyethyl)ethylenediamine (hydet-en) with copper, [Cu(NCS) <inf>2</inf>(C<inf>4</inf>H<inf>12</inf>N<inf>2</inf>O)], the Cu atom lies in a distorted square-pyramidal environment, coordinated by four N atoms in the basal plane and an apical O atom. The hydet-en ligand is N,N,O-tridentate, in contrast to the disposition in previously studied complexes, while the isothiocyanate ions act as N-atom donor ligands. The monomeric units are linked to one another by hydrogen bonds. © 2005 International Union of Crystallography.
