Lead-rich carboxylate-substituted titanium–lead oxo clusters

摘要

AbstractThe carboxylate-substituted mixed-metal oxo clusters Pb6Ti6O9(acetate)(methacrylate)17 and Pb4Ti8O10(OiPr)18(acetate)2 contain a higher number of lead atoms in the cluster core than previously reported compounds. The metal atoms in both clusters are arranged in three layers of different composition, which are connected through oxygen, propionate and/or carboxylate bridges.
