Complexes of the formula [(ηn-ring)MCl(κ3N,O,S-L)][SbF6] (6Sb–8Sb), in which the cysteine derivative acts as a tridentate chelate ligand, can be prepared by adding one equivalent of AgSbF6 to the solutions of compounds 5 or to the mixtures of complexes 3/6Cl and 4/7Cl. The amide proton of compounds 8aSb and 8bSb can be removed by addition of NaHCO3 affording the neutral complexes [(ηn-ring)M(κ3N
