The complete mol-ecule of the title complex, [Ni(C(19)H(21)N(2)OS(2))(2)], is generated by the application of twofold symmetry. The Ni(II) atom is N,S-chelated by two hydrazinecarbodithio-ate ligands, which provide an N(2)S(2) donor set that defines a distorted square-planar geometry, the S atoms being approximately cis. The conformation of the chelate ring is an envelope with the Ni(II) atom being the flap atom. The dihedral angle between the least-squares planes through the chelate rings = 30.10 (6)°. Supra-molecular chains propagated by glide symmetry along the c axis and mediated by C-H⋯N contacts feature in the crystal packing.
标题配合物[Ni(C₁₉H₂₁N₂OS₂)₂]的完整分子通过二重对称性生成。Ni(II)原子由两个肼基二硫代甲酸盐配体进行N,S-螯合,这两个配体提供了一个N₂S₂供体集,定义了一个扭曲的平面正方形几何构型,S原子近似为顺式。螯合环的构象为信封式,Ni(II)原子为瓣原子。通过螯合环的最小二乘平面之间的二面角为30.10 (6)°。晶体堆积中存在沿c轴通过滑移对称性传播并由C—H⋯N接触介导的超分子链。
