bond orbital (NBO) analysis has shown an analogous bonding scheme in the “Rh2(μ-CO)P2” subunit of complexes 4 and 7. Although both complexes can be formally described as composed of a Rh(III)–Rh(III) unit, assuming a ketonic character of the bridging carbonyl ligand, the natural charges on the rhodium atoms and the WBI indexes for the Rh–Rh and CO bonds points to electronically unsaturated metal centers
