[Ni(PPh3)2X2] (X = Cl, Br or NO3) on treatment with nitrosyl chloride in a benzene cyclohexane mixture as solvent, gave [Ni(OPPh3)XCl]2 (X = Cl, Br, NO3). Treatment of [Ni(OPPh3)XCl]2, [Ni(PPh3)XCl]2 (X = Cl, Br, SCN, NO3) or [Ni(OPPh3)ICl2] with triphenylphosphine gave [Ni(PPh3)2XCl]. The compounds obtained were characterised by analyses, infrared and visible spectral studies, magnetic moment and conductivity measurements. It is proposed that the dimeric compounds have distorted tetrahedral environment around the nickel atom with chloro-bridging. The compounds, [Ni(PPh3)2XCl] (X = Br, I, or NO3), have tetrahedral structures whereas [Ni(PPh3)2(NCS)Cl] is square-planar.
