Tetrakis[μ2-5-nitro-2-(phenylsulfanyl)benzoato-κ2O:O′]bis[(acetonitrile-κN)copper(II)]

Abstract

The title compound, [Cu2(μ2-O2CC12H8NO2S)4(CH3CN)2], consists of a dinuclear and centrosymmetric complex based on two CuII atoms coordinated by four 5-nitro-2-phenylsulfanyl-benzoate anions and two acetonitrile ligands. Each benzoate anion acts as a bis-monodentate ligand while each acetonitrile acts as a monodentate ligand, leading to a square-pyramidal NO4 coordination environment for each CuII atom with the acetonitrile N atom at the apex. The intramolecular Cu...Cu distance in the dimer is 2.6478 (3) Å. The cohesion of the crystal structure is ensured by (phenyl)C—H...O(nitro) hydrogen bonds and (phenyl)C—H...π interactions.
