Abstract: The crystal structure of the title compound, [Ni(C14H8F2S2)2] (I), reveals averaged S—C [1.708 (2) Å] and C—Cchelate [1.395 (4) Å] bond lengths that are consistent with radical monoanionic ligands paired with a divalent Ni2+ ion. Molecules of I associate as dyads via intermolecular Ni...S close contacts of 3.396 (2) Å. This close association is enabled by a bending of both dithiolene ligands to the same side and away from the NiS4 planar interior such that the angle between the seven atom mean planes defined by each NiS2C2 ring and the first C atom of each aryl substituent is 22.91 (8)°. These dyads form sheets in the bc plane that are held together in part by intermolecular C—H...F hydrogen bonds of 2.47 (4) Å.
