Phosphine complexes of zirconium and hafnium. Synthesis, structure, and fluxional behavior of the trimelthyl derivatives MMe{sub 3}[N(SiMe{sub 2}CH{sub 2}PR{sub 2}){sub 2}] (R = Me, Pr{sup 1}, Bu{sup t}). Evidence for a bicapped-tetrahedral geometry

The addition of 3 equiv of methyl Grignard (MeMgCl) to the amidodiphosphine derivatives MCl{sub 3} [N-(SiMe{sub 2}CH{sub 2}PR{sub 2}){sub 2}] (M = Zr, Hf; R=Me, Pr{sup i}, Bu{sup t}) generates the corresponding trimethyl complexes MMe{sub 3}[N-(SiMe{sub 2}CH{sub 2}PR{sub 2}){sub 2}]. The solution structures and fluxional behavior of these molecules along with the X-ray structure of HfMe{sub 3}[N(SiMe{sub 2}CH{sub 2}PMe{sub 2}){sub 2}] are presented. 32 refs., 1 fig., 4 tabs.
