Bis[1,2-bis(4-fluorophenyl)ethylene-1,2-dithiolato(1−)]nickel(II)
The crystal structure of the title compound, [Ni(C<sub>14</sub>H<sub>8</sub>F<sub>2</sub>S<sub>2</sub>)<sub>2</sub>] (<b>I</b>), reveals averaged S-C [1.708 (2) Å] and C-C<sub>chelate</sub> [1.395 (4) Å] bond lengths that are consistent with radical monoanionic ligands paired with a divalent Ni<sup>2+</sup> ion. Mol-ecules of <b>I</b> associate as dyads <i>via</i> inter-molecular Ni⋯S close contacts of 3.396 (2) Å. This close association is enabled by a bending of both di-thiol-ene ligands to the same side and away from the NiS<sub>4</sub> planar inter-ior such that the angle between the seven atom mean planes defined by each NiS<sub>2</sub>C<sub>2</sub> ring and the first C atom of each aryl substituent is 22.91 (8)°. These dyads form sheets in the <i>bc</i> plane that are held together in part by inter-molecular C-H⋯F hydrogen bonds of 2.47 (4) Å.
