Synthesis and Determination of Crystal and Molecular Structure of {Bispyridine-bis[4-methoxyphenyl(3-methylbutyl)dithiophosphinato]}nickel(II)

抄録

The addition of trans-bis[4-methoxyphenyl(3-methylbutyl)dithiophosphinato]nickel(II) with pyridine (py) gave the {bispyridine-bis[4-methoxyphenyl(3-methylbutyl)dithiophosphinato]}nickel(II) [Ni(Py)₂(L)₂] complex. The structure of the complex has been characterized by X-ray diffraction. Ni(II)dithiophosphinato complex was reported¹ to be of squareplanar geometry while the latter compound was of a octahedral coordination geometry. It crystallizes in monoclinic system, space group P2₁/n, with lattice parameters a = 12.4968(12)Å, b = 9.7051(10)Å, c = 16.0975(17)Å, (β = 101.734(8)°, Z = 2, (μ = 0.84 mm^-1, S = 1.003, R = 0.0437 and wR = 0.1017 for 3562 observed reflections. The structure was solved by direct methods using the SHELX-97 program and refined on F².
