Bis[1,2-bis-(4-chloro-phen-yl)-ethyl-ene-1,2-dithiol-ato(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 as pairs of mol-ecules disposed about an inversion center at the bc face of the cell. Close inter-molecular 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 mol-ecular 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 inter-molecular contacts. In the larger packing arrangement, sheets of mol-ecules extend in the direction of the ac face diagonal.
