[Cp*Rupb11](3-)And [Cu@Cp*Rupb11](2-): Centered And Non-Centered Transition-Metal Substituted Zintl Icosahedra

Cluster anions [Cp*RuPb11](3-)(1) and [Cu@Cp*RuPb11](2-)(2) represent the first vertex-substituted zintl icosahedra and1is the first non-centered zintl icosahedron isolated in the condensed phase. Complexes1and2are both 12-vertex, 26-electroncloso-clusters withC(5v)point symmetry and are static on the(207)Pb NMR time scale in solution.
