The N‐heterocyclic carbene–phosphinidene adduct IPrPSiMe 3 is introduced as a synthon for the preparation of terminal carbene–phosphinidyne transition metal complexes of the type [(IPrP)ML n ] (ML n =(η 6 ‐p‐cymene)RuCl) and (η 5 ‐C 5 Me 5 )RhCl). Their spectroscopic and structural characteristics, namely low‐field 31 P NMR chemical shifts and short metal–phosphorus bonds, show their similarity with arylphosphinidene complexes. The formally mononegative IPrP ligand is also capable of bridging two or three metal atoms as demonstrated by the preparation of bi‐ and trimetallic RuAu, RhAu, Rh 2 , and Rh 2 Au complexes.
