Reaction of [MF(CO)(PPh3)2] (M = Rh or Ir) with bulky aromatic thiols ArSH gave the binuclear complexes [M2(μ-SAr)2(CO)2(PPh3)2] (M = Rh, SAr = SC6H2Pri3-2,4,6 or SC6H3Me2-2,6) and mononuclear complexes [M(SAr)(CO)(PPh3)2] (M = Rh or Ir, SAr = SC6H3Cl2-2,6 or SC6H4SiPh3-2; M = Ir, SAr = SC6H2Pri3-2,4,6 or SC6H3Me2-2,6. The crystal structure of [Rh2(μ-SC6H3Pri3-2,4,6)2(CO)2(PPh3)2] showed a binuclear
