Abstract
The electrochemical oxidation of gallium or cobalt in the presence of CH3CN + (C6H5)3P + HX (X Cl, Br, I) yields, in a single step, the (C6H5)3PH+ salts of Ga2X62− (X Cl, Br, I) or CoCl42− in good crystalline form. X-ray crystallogrpahic studies gave the bond lengths and angles of the cation, and confirmed the presence of the Ga2X62− anion for XCl or I. Vibrational spectra provide diagnostic criteria for distinguishing (C6H5)3PH+ from ligated (C6H5)3P.
