Abstract

Purple crystals of bis(O,O'-neopentylene dithiophosphato)nickel(II), Ni[S2POCH2CMe2CH2O](2) and bis(O,O'-hexylene dithiophosphato)nickel(II), Ni[S2POCMe2CH2CHMeO](2) were obtained by layering benzene solutions of the complexes with ether and maintaining the samples at room temperature. The molecular structures of Ni[S2POCH2CMe2CH2O](2) and Ni[S2POCMe2CH2CHMeO](2) were determined by single-crystal X-ray diffraction. Ni[S2POCH2CMe2CH2O](2) crystallizes as monoclinic in the space group P2(1)/c with cell parameters a = 7.051(2) angstrom, b = 6.453(2) angstrom, c = 19.686(6) angstrom, beta = 99.45(3)degrees, V = 883.6(5) angstrom(-3), Z = 2, R = 0.0251, R-w = 0.0599. Ni[S2POCMe2CH2CHMeO](2) crystallizes as triclinic in the space group P-1 with cell parameters a = 8.394(5) angstrom, b = 11.070(5) angstrom, c = 12.124(5) angstrom, alpha = 71.287(5)degrees, beta = 76.227(5)degrees, gamma = 88.319(5)degrees, V = 1035.0(9) angstrom(-3), Z = 2, R = 0.0655, R-w = 0.1545. In both complexes the environment around nickel is distorted square planar.
