The mixed-metal species [Gd2Zr6(μ4-O)2(μ-OAc)6(μ-OPri)10(OPri)10] (1) was obtained by reacting anhydrous gadolinium acetate with [Zr(OPri)4(PriOH)]2. Its X-ray structure analysis reveals two Zr3Gd(μ4-O)(μ-OAc)2(OPri)10 tetrahedral clusters associated via Gdμ-OAc linkages. The zirconium and gadolinium centres are hexa- and hepta-coordinated, respectively. The analogous yttrium derivative (2) was obtained by a similar route and characterized by microanalysis, IR, 1H and 13C NMR spectroscopies. Control of the stoichiometry between the metals can be achieved by varying the nature of the alkoxo group. Hydrolysis-polycondensation reactions proceed via differential hydrolysis and offered cubic zirconia containing various amounts of lanthanide oxides depending on the stoichiometry between the metals. © 1993.
