Bis[1,2-bis-(4-tert-butyl-phen-yl)ethyl-ene-1,2-di-thiol-ato(1-)]nickel(II) pentane 0.25-solvate.

Abstract

The title compound, [Ni(C22H26S2)2], 1, is a square-planar D 2h -symmetric compound that occurs on a general position in non-centrosymmetric tetra-gonal P41212 (No. 92) with ¼ eq of n-pentane (C5H12) as co-crystallite. Intra-ligand bond lengths show the di-thiol-ene ligands to be in their half-oxidized radical monoanionic form. Inter-molecular t Bu-C-H⋯arenecentroid and t Bu-C-H⋯NiS2C2 centroid close contacts guide the packing arrangement for 1.
