Abstract: The new complex compounds of bivalent nickel with dithiocarbamates, triphenylphosphine and isothiocyanate as mixed ligands of the composition Ni(NCS)(R¹R²dtc)(PPh₃) and Ni(NCS)(Ldtc)(PPh₃), respectively, have been isolated. By the X-ray analysis of Ni(NCS)(but₂dtc)(PPh₃) the distorted square-planar coordination around of nickel (NiS₂PN) was confirmed. The monocrystal is monoclinic and the basic data are as follows: Space group of symmetry P2₁/c; a = 9.891(1) 10^-10 m; b = 14.661(2) 10^-10 m; c = 21.002(3) 10^-10 m; β = 102.65(1)°; V = 2972.3 10^-30 m3; Z = 4; ρ_x-ray = 1.304 g cm^-3;  ρ_exp = 1.32 g cm^-3; R = 3.90%; R_w = 4.21%.
