[Cp*RuPb11]3− and [Cu@Cp*RuPb11]2−: centered and non-centered transition-metal substituted zintl icosahedra

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 C_5v point symmetry and are static on the ²⁰⁷Pb NMR time scale in solution.
