A new route to iron carbonyls has enabled synthesis of 57Fe-labeled [NiFe] hydrogenase mimic (OC)357Fe(pdt)Ni(dppe). Its study by nuclear resonance vibrational spectroscopy revealed Ni–57Fe vibrations, as confirmed by calculations. The modes are absent for [(OC)357Fe(pdt)Ni(dppe)]+, which lacks Ni–57Fe bonding, underscoring the utility of the analyses in identifying metal–metal interactions.
