A family of lead clusters with precious metal cores
Abstract
Many Zintl ions with a single endohedrally encapsulated transition metal ion are known, but relatively few where clusters of two or more metals are present. Here, the authors report the synthesis and characterization of two clusters, [Au8Pb33]6− and [Au12Pb44]12−, which contain Au8 and Au12 cores surrounded by Pb shells.
