Trans-Tetraaquabis(p-Nitrobenzoxasulfamato)Cobalt(II)

Abstract

The structure of the title complex consists of neutral molecules of [Co(nbs)<inf>2</inf>(H<inf>2</inf>O)<inf>4</inf>] (nbs is the p-nitrobenzoxasulfamate anion, C<inf>6</inf>H<inf>3</inf>N<inf>2</inf>O <inf>5</inf>S-). The Co2+ ion occupies an inversion centre and exhibits a distorted octahedral geometry, involving two monodentate nbs (N<inf>imine</inf>) anions and four water molecules. The crystal structure is stabilized by hydrogen bonding 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.
