Tri-metallic deltahedral Zintl ions: experimental and theoretical studies of the novel dimer [(Sn6Ge2Bi)2]4−†
Abstract
We report the synthesis, characterization, and computational rationalization of the first trimetallic deltahedral Zintl ions. The novel nine-atom clusters were structurally characterized as dimers of [(Sn6Ge2Bi)2]4− with Ge–Ge intercluster bonds. They are synthesized either by reacting bimetallic clusters (Sn9−xGex)4− with BiPh3 or by direct
