While anhydrous nickel(II) chloride reacts with CH2(Ph2P=NSiMe3)2 to afford the pseudotetrahedral complex NiCl2[CH2(Ph2P=NSiMe3) 2] (2), the analogous reaction with anhydrous nickel(II) iodide gives the structurally related complex NiI2[CH2(PPh2=NSiMe3)(PPh 2=NH)] (3) in which one of the trimethylsilyl groups of 1 has been replaced by hydrogen. Another reaction in which the fragmentation of 1 occurs is that with the hydrate NiCl2·6H2O; in this case a square-planar nickel(II) complex of composition [Ni{Ph2PCH2PPh2(=NH)}2]Cl 1.25(NO3)0.75 (4) was identified as one of the products. The phosphonium salt [Ph2P(NH2)NPPh2(CH3)]I (5) is found to be a major product of the reaction between 3 and CO. The structures of 2-5 have been established by X-ray crystallography.
