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

The title compound, [Ni(S2C2(C6H4-p-Cl)2)2] or [Ni(C14H8Cl2S2)2], crystallizes in the triclinic space group PUnlabelled Image 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.Unlabelled Image
