Trans-Bis(Ethylenediamine)Bis(p-Nitrobenzoxasulfamato)Copper(II)

Abstract

The structure of trans-[Cu(nbs)<inf>2</inf>(en)<inf>2</inf>] [nbs is the p-nitrobenzoxasulfamate anion (C<inf>6</inf>H<inf>3</inf>N<inf>2</inf>O <inf>5</inf>S)<inf>-</inf> and en is ethylenediamine, C<inf>2</inf>H <inf>8</inf>N<inf>2</inf>] consists of neutral molecules. The Cu2+ ion occupies an inversion centre and exhibits an elongated distorted octahedral geometry, with two monodentate nbs anions and two bidentate en ligands. Both nbs ligands are O-coordinated via an O atom of the nitro group. The crystal structure is stabilized by hydrogen bonds and weak aromatic π-π stacking interactions between the benzene rings of nbs ligands, forming a three-dimensional network. © 2004 International Union of Crystallography Printed in Great Britain - all rights reserved.
