A new type of pincer ligand (1) featuring an Sb(I) center and two pendent amine arms has been developed. The single electron oxidation of 1 produces a dicationic distibine (2). Crystallographic and computational investigations indicate that 2 gains stabilization from intramolecular π-π interactions and second-sphere coordination. The reactions of 2 with a disulfide and Co2(CO)8 reveal its dual redox reactivity associated with the oxidation of the Sb-Sb bond and the reduction of the cationic Sb(II) centers.
