The triazenide-bridged tetracarbonyls [(OC)2Rh(-p-MeC 6H4NNNC6H4Me-p)2M(CO) 2] (M = Rh or Ir) undergo oxidative addition of iodine across the dimetal centre, giving the [RhM]4+ complexes [I(OC) 2Rh(-p-MeC6H4NNNC6H 4Me-p)2M(CO)2I], structurally characterised for M = Ir. The anionic tricarbonyl iodide [I(OC)Rh(-p-MeC6H 4NNNC6H4Me-p)2Rh(CO) 2]- forms [I2(OC)Rh(-p-MeC6H 4NNNC6H4Me-p)2Rh(CO)I]- by initial one-electron transfer whereas the analogous tricarbonyl phosphine complexes [(OC)(Ph3P)Rh(-p-MeC6H4NNNC 6H4Me-p)2M(CO)2] (M = Rh or Ir) undergo bridge cleavage, giving mononuclear [Rh(p-MeC6H 4NNNC6H4Me-p)I2(CO)(PPh 3)] and dimeric [I(OC){RNNN(R)C(O)}M(-I)2M{C(O)N(R)NNR} (CO)I] (M = Rh or Ir, R = C6H4Me-p) in which CO has been inserted into a metal-nitrogen bond.
