An osmium(II) complex of a novel hexadentate diphosphinobis(disulfide) macrocyclic ligand with pendant thiolate groups

Dilworth JR, Zheng Y, Miller JR

The complex [OsCl2(PPh3)3] reacts with P(C6H4SH-2)3 to give the neutral osmium(II) complex [OsL], where L has been confirmed by an X-ray crystal structure determination to be a hexadentate ligand formed by the oxidative coupling of two P(C6H4S-2)3 ligands via two disulfide bonds.
