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.

The preparation and characterization of a range of phenyl complexes of ruthenium(II) are reported.For many of the complexes there is a substantial barrier to rotation of the phenyl ligand about the metal-phenyl bond, and n.m.r. studies have shown how the rate of rotation is affected by changes in the ligands in the complexes.Reaction of complexes with phosphorus or arsenic ligands L provides a convenient route to : 31P and 13C n.m.r. studies have demonstrated the sequence of steps involved and the stereochemistry of the intermediates, showing the influence of the trans-labilizing and trans-directing effects of the phenyl ligand.
