Bis[1,2-bis(4-chlorophenyl)ethylene-1,2-dithiolato(1–)]nickel(II)

Abstract

The title compound, [Ni(S2C2(C6H4-p-Cl)2)2] or [Ni(C14H8Cl2S2)2], crystallizes in the triclinic space group P\overline{1} as pairs of molecules disposed about an inversion center at the bc face of the cell. Close intermolecular C—H...S (2.884 Å) and C—H...Ni (3.032 Å) contacts that are less than the sum of the van der Waals radii appear to induce slight bowing of the molecular planes toward one another. The angles at which the four p-ClC6H4- rings join the NiS2C2 chelate rings [39.37 (9)– 53.41 (6)°] are similarly influenced by these intermolecular contacts. In the larger packing arrangement, sheets of molecules extend in the direction of the ac face diagonal.
