The crystal structure of the title compound, [Ni(CHFS)] (), reveals averaged S-C [1.708 (2) Å] and C-C [1.395 (4) Å] bond lengths that are consistent with radical monoanionic ligands paired with a divalent Ni ion. Mol-ecules of associate as dyads 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 planar inter-ior such that the angle between the seven atom mean planes defined by each NiSC ring and the first C atom of each aryl substituent is 22.91 (8)°. These dyads form sheets in the plane that are held together in part by inter-molecular C-H⋯F hydrogen bonds of 2.47 (4) Å.
标题化合物[Ni(CHFS)]（）的晶体结构显示，平均S-C键长为[1.708 (2) Å]，C-C键长为[1.395 (4) Å]，这与与二价镍离子配对的自由基单阴离子配体一致。分子以二元体形式缔合，分子间Ni⋯S的近距离接触为3.396 (2) Å。这种紧密缔合是通过两个二硫代烯配体向同一侧弯曲并远离NiS平面内部实现的，使得由每个NiSC环定义的七个原子平均平面与每个芳基取代基的第一个C原子之间的夹角为22.91 (8)°。这些二元体在平面内形成片层，部分通过2.47 (4) Å的分子间C-H⋯F氢键结合在一起。
