Abstract

Cluster anions [Cp*RuPb11]3- (1) and [Cu@Cp*RuPb11]2- (2) represent the first vertex-substituted zintl icosahedra and 1 is the first non-centered zintl icosahedron isolated in the condensed phase. Complexes 1 and 2 are both 12-vertex, 26-electron closo-clusters with C5v point symmetry and are static on the 207Pb NMR time scale in solution.
