Abstract
ABSTRACTLead(II) oxides are involved in various advanced materials. Their high volatility as compared to that of other elements makes chemical routes to such materials especially attractive. Various synthetic routes to lead(II) alkoxides have therefore been estimated. They display a strong tendency to undergo spontaneous condensation reactions, giving oxoalkoxides Pb4O(OR)6 (R = tBu, iPr, Et). Reaction between Pb4O(OEt)6 and [Nb(OEt)5l2 does not proceed by simple addition of the alkoxides, but the lead tetranuclear oxoalkoxide is transformed to a hexanuclear one, Pb6O4 (OEt)4 , whose oxo ligands bear Nb(OEt)5 moieties, the overall formula being Pb6O4 (OEt)4 [Nb(OEt)5]4 1. The stoichiometry between the two metals corresponds to that of the PNM ceramic, and 207Pb NMR has been used as a tool to study the reactivity of 1 in the presence of various modifiers and magnesium ethoxide.
