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

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)](+),...

description 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.
