The results suggest that metal site- and spin-selective XAES on [FeFe] hydrogenase protein and active site models may provide a powerful tool to study intermediates under reaction conditions.
Spectroscopically characterized intermediates of catalytic H2 formation by [FeFe] hydrogenase models
This review compiles species that are known or potential intermediates in the catalytic formation of H2 by diiron dithiolate complexes inspired by the active site of the [FeFe] hydrogenases. The data…
Catalytic hydrogen evolution from mononuclear iron(II) carbonyl complexes as minimal functional models of the [FeFe] hydrogenase active site.
How much iron does it take? Mononuclear complexes [FeII(3,6-R2bdt)(CO)2(PMe3)2] (bdt=1,2-C6H4(S−)2; R=H, Cl) can be reversibly protonated at the sulfur ligands, can catalyze the electrochemical red…
High-turnover photochemical hydrogen production catalyzed by a model complex of the [FeFe]-hydrogenase active site.
Investigations of photo- and electrocatalytic hydrogen production with natural and synthetic molecular catalysts provide detailed kinetic and mechanistic information on the catalyst itself, and it is possible to distinguish between alternative catalytic pathways and to extract rate constants for individual steps of catalysis.

A Biomimetic Pathway for Hydrogen Evolution from a Model of the Iron Hydrogenase Active Site and its consequences are illustrated.
Introducing a dark reaction to photochemistry: photocatalytic hydrogen from [FeFe] hydrogenase active site model complexes.
Covalently linked dyads, supramolecular assemblies and multi-component systems will be examined with an emphasis on mechanistic electron transfer schemes, the properties of the individual components, their scope and their potential limitations.
A model of the [FeFe] hydrogenase active site with a biologically relevant azadithiolate bridge: a spectroscopic and theoretical investigation.
Convincing evidence for the presence of a nitrogen atom in the dithiolate bridge of the active site of native [FeFe] hydrogenases (B) is provided by a spectroscopic, electrochemical, and theoretica…
Model of the iron hydrogenase active site covalently linked to a ruthenium photosensitizer: synthesis and photophysical properties.
IR and electrochemical studies reveal that the nitrogen heteroatom of the ADT bridge has a marked influence on the electronic properties of the [Fe2(CO)6] core.
