摘　　要：O-（p-tolyl）dithiophosphato nickel complex [Ni（S2P{O}OC6HaCH3-p）（dppv）] has been synthesized by the treatment of （dppv）NiCl2 （dppv = Ph2PCH=CHPPh2） with （p-CH3C6HaO）2P{S}SH＇Et2NH in THF. The new complex was fully characterized by elemental analysis, IR, 1H NMR, 31p NMR spectroscopies and thermo-gravimetric analysis. The molecular structure of the complex was established by X-ray crystallography. The crystal crystallizes in monoclinic, space group P21/c with a = 9.2739（5）, b = 17.8803（8）, c = 20.1879（12） A, fl = 93.269（5）, V = 3342.1（3） A3, Z = 4, C33H29NiO2P3S2, Mr = 673.30, Dc = 1.338 g/cm3, F（000） = 1392 and #（MoKa） = 0.877 rnm-l. The final R = 0.0578 and wR = 0.1045 for 4138 observed reflections with 1 〉 20（/） and R = 0.1050 and wR = 0.1204 for all data. The Ni centre atom adopts a NiP2S2 square-planar geometry with two phosphorus atoms from the dppv ligand and two sulfur atoms from the O-（p-tolyl）dithiophosphate ligand. The most interesting structural feature of the title complex resides in its 1D helical chain structure constructing via intermolecular C-H＇＂O secondary interactions along the b-axis. The adjacent helical chains running in opposite directions are connected into a 1D double-stranded helical chain and further linked into a 2D supramolecular network by weak C-H.--C interaction.O-（p-tolyl）dithiophosphato nickel complex [Ni（S2P{O}OC6HaCH3-p）（dppv）] has been synthesized by the treatment of （dppv）NiCl2 （dppv = Ph2PCH=CHPPh2） with （p-CH3C6HaO）2P{S}SH＇Et2NH in THF.
