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

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 π–π stacking interactions between the benzene rings of nbs ligands, forming a three-dimensional network.
