Purple-coloured, tetra-coordinated Ni(II) complexes, Ni[S 2P(OR)2]2 (R = o-, m-, p-OC6H 4Me, Ph and CH2Ph) have been obtained by reaction of NiCl2 with salts of corresponding O,O′-diaryl(dibenzyl) dithiophosphates and have been characterized by elemental analysis, UV, IR, 1H, and 31P NMR spectroscopy. Trends in the data are discussed. The crystal structures of Ni[S2P(OC6H 4Me-o)2]2, Ni[S2P(OC 6H4Me-m)2]2 and Ni[S 2P(OCH2Ph)2]2 are also described. Ni[S2P(OC6H4Me-o)2]2 crystallizes as monoclinic in the space group P21/n with cell parameters a = 9.069(2), b = 13.503(2), c = 23.735(4) ?, α = 90.00°, β = 90.11(1)°, γ = 90.00°, V = 2906.6(8) ?-3, Z = 4, R = 0.0351, Rw = 0.0787, Ni[S 2P(OC6H4CH3-m)2] 2 as triclinic in the space group P1? with cell parameters a = 9.4675(4), b = 12.8568(5), c = 13.1174(6) ?, α = 88.810(4)°, β = 83.416(5)°, γ = 73.711(4)°, V = 1522.4(1) ?-3,Z = 2, R = 0.0354, Rw = 0.0830, and Ni[S 2P(OCH2Ph)2]2 as triclinic in the space group P1? with cell parameters a = 10.887(2), b = 14.081(3), c = 16.238(3) ?, α = 72.70(3)°, β = 76.57(3)°, γ = 72.76(3)°, V = 2241.4(8) ?-3, Z = 2, R = 0.0365, R w = 0.0785. Each of these has a distorted square-planar geometry around nickel with MS4 coordination environment.
