Bis[1,2-bis(4-tert-butylphenyl)ethylene-1,2-dithiolato(1−)]nickel(II) pentane 0.25-solvate

Abstract

The title compound, [Ni(C22H26S2)2], 1, is a square-planar D2h-symmetric compound that occurs on a general position in non-centrosymmetric tetragonal P41212 (No. 92) with ¼ eq of n-pentane (C5H12) as co-crystallite. Intraligand bond lengths show the dithiolene ligands to be in their half-oxidized radical monoanionic form. Intermolecular tBu-C—H...arenecentroid and tBu-C—H...NiS2C2 centroid close contacts guide the packing arrangement for 1.
