Intramolecular dynamics of [Rh4(CO)6(μ-PPh2)4] in solution

Abstract

A 103Rh, 31P and 13C NMR study of [Rh4(CO)6(μ-PPh2)4] in CD2Cl2 indicates that the strongly bonded, bridging, anionic ligand PPh2− takes part in the site exchange of the carbonyl ligands and is actually mobile about the metallic surface of this cluster compound.
