Inorganic Ligands Sb3- and Bi3-: Synthesis and Crystal Structures of Complexes with Mixed-Ligand Cluster Cores {Re4Se3Sb}7+ and {Re4Se3Bi}7

Abstract

The reactions of ReI₃, Se, and KCN with Sb₂O₃ or Bi₂O₃ at elevated temperature led to the formation of two new tetrahedral clusters with mixed-ligand cluster cores {Re₄Se₃Sb}⁷⁺ and {Re₄Se₃Bi}⁷⁺. They are the first examples of complexes with either Sb^3- or Bi^3- ligands, which have never been previously described in the literature.
