1-(3,4-Dichlorobenzyl)pyridinium bis-(2-sulfanylidene-1,3-dithiole-4,5- dithiolato-κ2 S,S′)nickelate(III)

Abstract

The title compound, (C12H10Cl2N)[Ni(C 3S5)2], is an ion-pair complex consisting of 1-(3,4-dichloro-benz-yl)pyridinium cations and [Ni(dmit)2] anions (dmit = 2-sulfanylidene-1,3-dithiole-4,5-dithiol-ate). In the anion, the Ni III ion exhibits a square-planar coordination involving four S atoms from two dmit ligands. In the crystal, weak S⋯S [3.368 (2) and 3.482 (3) Å], Ni⋯S [3.680 (2) Å] and Cl⋯S [3.491 (2) Å] inter-actions and C - H⋯S hydrogen bonds lead to a three-dimensional supra-molecular network. © Guang-Xiang Liu 2011.
