Abstract

The new iron carbonyl cyanide trans-[Fe(CN)₂(CO) ₃]^2-, [2]^2-, forms in high yield via photosubstitution of Fe(CO)₅ with 2 equiv of Et₄NCN. Protonation of [2]^2- generated [HFe(CN)₂(CO) ₃]^-, [2H]^-, the first H-Fe-CN-CO species. Further protonation gives dihydrogen. This simple system provides insights into hydrogen evolution by the hydrogenase enzymes, which also feature H-Fe-CN-CO centers.
