Abstract
Abstract The halide salts of the mono-quaternized ditertiary phosphines, 1,2-bis(diphenylphosphino)ethane and 1,1-bis(diphenylphosphino)methane, abbreviated as (PCH 2 CH 2 P + ) and (PCH 2 P + ) respectively, react under anhydrous conditions with the cobalt(II) and nickel(II) halides, forming crystalline compounds of stoichiometry MX 2 . (PCH 2 CH 2 P + X and MX 2 . (PCH 2 P + )X, where M = Co II and Ni II and X = Cl, Br, I. On the basis of their vibrational and d-d electronic spectra, magnetic properties, and X-ray powder diffraction patterns. these compounds are formulated as the high-spin, four-coordinate species [MX 3 (PCH 2 CH 2 P + )] and [MX 3 (PCH 2 P + )], having a pseudo-tetrahedral stereochemistry with C 3v symmetry.
