The complex adducts [M(acac)2(PhHgOHgPh)]2 (M = Co, Ni) have been obtained by incorporation of PhHgOH into the coordination sphere of M(acac)2 at ambient temperature. The X-ray crystal structure of [Ni(acac)2(PhHgOHgPh)(Et2O)]2 (1c) reveals a dimeric nickel complex coordinated by the acetylacetonate oxygen and the bridging oxygen of bis(phenylmercuric) oxide. Refluxing a THF solution of compound 1c gave diphenylmercury, HgO, and Ni(acac)2(THF)2. With PhHgOH or PhHgSH the symmetrization reactions also occurred when catalytic amounts of Ni(acac)2 were used. In contrast, triphenyltin derivatives (hydroxide, acetate, oxide) on treatment with M(acac)2 in aqueous THF gave the stable complexes [M(acac)2(Ph3SnOH)]2 (M = Co, Ni). The structure of [Ni(acac)2(Ph3SnOH)]2 (2) was also determined by X-ray crystallography.
