trans-Tetraaquabis(p-nitrobenzoxasulfamato)cobalt(II)

Abstract

The structure of the title complex consists of neutral molecules of [Co(nbs)(2)(H2O)(4)] (nbs is the p-nitrobenzoxasulfamate anion, C6H3N2O5S-). The Co2+ ion occupies an inversion centre and exhibits a distorted octahedral geometry, involving two monodentate nbs (N-imine) anions and four water molecules. The crystal structure is stabilized by hydrogen bonding and weak aromatic pi-pi stacking interactions between the benzene rings of nbs ligands, forming a three-dimensional network.
