New rhodium and iridium complexes, with the formula [MCl (PBz3)(cod)][M= Rh (1), Ir (2)] and [M (PBz3) 2 (cod)] PF6 [M= Rh (3), Ir (4)](cod= 1, 5-cyclooctadiene), stabilized by the tribenzylphosphine ligand (PBz3) were synthesized and characterized by elemental analysis and spectroscopic methods. The molecular structures of 1 and 2 were determined by single-crystal X-ray diffraction. The addition of pyridine to a methanol solution of 1or 2, ...
