trans-Bis(ethylenediamine)bis(p-nitrobenzoxasulfamato)copper(II)

C. Kazak, V. T. Yilmaz and T. K. Yazicilar

Abstract: The structure of trans-[Cu(nbs)₂(en)₂] [nbs is the p-nitrobenzoxasulfamate anion (C₆H₃N₂O₅S)^- and en is ethylenediamine, C₂H₈N₂] 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 - stacking interactions between the benzene rings of nbs ligands, forming a three-dimensional network.
