1 Chemistry

The preparation of soluble organometallic hydroxides is a key step in the preparation of organometallic oxides containing the heterobimetallic M-O-M' unit. Compounds of composition LMOH where M is a Main Group metal (Ca, Sr, Al, Ga, Ge, Sn) and transition metal (Zr, Hf) are summarized. The reactions of Cp3Ln (Ln = Yb, Dy, Er, Sm) with several hydroxides to yield compounds with the skeletons M(µ-O)Ln and M(µ-OH)Ln are reported. The application of the latter compounds in Є-caprolactone polymerization is discussed. An unforeseen formation of a chlorine-centered cluster of composition [(Me3Si)2NC(NCy)2SmCl2]5(THF)2 is reported.
