New tris-amidinate actinide (Th, U) complexes containing a rare O-bound terminal phosphaethynolate (OCP-) ligand were synthesized and fully characterized. The cyanate (OCN-) and thiocyanate (SCN-) analogs were prepared for comparison and feature a preferential N-coordination to the actinide metals. The Th(amid)(3)(OCP) complex reacts with Ni(COD)(2) to yield the heterobimetallic adduct (amid)(3)Th(mu- eta(1)(O): eta(2)(C, P)-OCP) Ni(COD) featuring an unprecedented reduced (OCP-) bent fragment bridging the two metals.
