Reactions of half-sandwich Co(III) complexes with heterocyclic thione ligands: η2-N, S coordination mode and formation of S–S bond

The reactions of Cp∗CoI2(CO) with heterocyclic thione ligands yields a η2-N, S coordination family of cobalt complexes for adjacent N, S donor atoms, and dinuclear disulfide cobalt complexes for opposite N, S donor atoms.
