Synthesis and vibrational spectroscopy of Fe-57-labeled models of [NiFe] hydrogenase: first direct observation of a nickel-iron interaction

A new route to iron carbonyls has enabled synthesis of 57Fe-​labeled [NiFe] hydrogenase mimic (OC)​357Fe(pdt)​Ni(dppe) (pdt = 1,​3-​propanedithiolate)​. Its study by nuclear resonance vibrational spectroscopy revealed Ni-​57Fe vibrations, as confirmed by calcns. 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.
