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; ρx-ray = 1.304 g cm-3;  ρexp = 1.32 g cm-3; R = 3.90%; Rw = 4.21%.
