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.Keywords
