X-ray structure analysis was performed on complex 3a, where the potential N,P-chelate ligand 2 was found to coordinate in a bidentate mode. The subsequent reaction of 3 with PPh3 and CO resulted in the dissociation of the N,P-chelate ligand 2 to yield the penta-coordinate metal complexes [(PPh3)2M(CO)3]+BF4−4 (M=Rh 4a, Ir 4b). The structure of 4a was determined by X-ray diffraction analysis, exhibiting
