Popis: Complexes of the type [(cod)MClL](cod = cyclo-octa-1,5-diene; M = Rh or Ir, L = Me3PS or Me2PhPS; M = Rh, L = Me2PhPSe or Me3AsS; M = Ir, L = MePh2PS), and related cations [(cod)ML2]+[M = Rh, L = Me3PS or Me2PhPS; M = Rh or Ir, L2= Ph2P(S)CH2P(S)Ph2] have been synthesised. The complexes [(cod)-IrClL](L = Me3PS or Me2PhPS) undergo oxidative-addition reactions with anhydrous HCl to give [(cod)Ir(H)-Cl2L]. For L = Me2PhPS a second product can be isolated, viz.[(cod)Ir(H)Cl2]2,C6H6. This is the only product for the reaction where L = MePh2PS. The hydrido-complexes [(cod)Ir(H)Cl2L] immediately eliminate HCl in water and ethanol. Reaction of iodine with the complexes [(cod)IrClL](L = Me3PS or MePh2PS) affords [(cod)IrCl(L)I2]. The complexes have been characterised by i.r. and n.m.r. spectroscopy.
