[1,4-Bis(diphenylphosphino)butane-P,P'](N,N'-diethyldithiocarbamato-S,S')nickel(II) Perchlorate

The title compound, [Ni(C₅H₁₀NS₂)(C₂₈H₂₈P₂)]ClO₄, is planar. The pairs of Ni-S [2.2089 (8) and 2.2075 (8) Å] and Ni-P [2.1945 (7) and 2.1932 (8) Å] bond lengths are respectively equal, and the P-Ni-P angle [95.12 (3)°] is large as a consequence of the flexible butyl chain between the two P atoms. The butyl chain lies on one side of the planar NiS₂P₂ chromophore and two of the phenyl rings are arranged laterally above the plane.
