摘要

A new route to iron carbonyls has enabled synthesis of ~(57)Fe-labeled [NiFe] hydrogenase mimic (OC)_3~(57)Fe(pdt)Ni(dppe). Its study by nuclear resonance vibrational spectroscopy revealed Ni-~(57)Fe vibrations, as confirmed by calculations. The modes are absent for [(OC)_3~(57)Fe(pdt)-Ni(dppe)]~+, which lacks Ni-~(57)Fe bonding, underscoring the utility of the analyses in identifying metal-metal interactions.
