Abstract

Metal alkoxides are often associated with more accessible precursors such as carboxylates, nitrates, B-diketonates, in chemical routes to multicomponent oxides. The molecular constitution of such solutions has been examined for systems based on niobium or zirconium. The heterometallic aggregates MNb2(μOAc)2(μ-0R)4(OR)6 (M = Cd, Mg), PbZr3, (μ4-0)(μ-0Ac)2(μ-0R)5(0R)5 and Gd2Zr6(μ4-O)2(μOAc)6(μOR)10(0R)10 R = iPr have been characterized by X-ray diffraction. Preliminary results on the hydrolysis experiments of these aggregates are given.
