Enzyme models on the catwalk! A series of new model complexes of the active site of [Fe]‐hydrogenase have been synthesized and characterized. These complexes are monomeric in solution, but dimeric in the solid state.

What is the channel? The thiolateligand in the five‐coordinate modelcomplex 1 of [Fe]‐hydrogenase is preferentially and reversibly protonated, even in the presence of an acyl ligand. The results suggest that the Cys176 thiolateligand in [Fe]‐hydrogenase can serve as the internal base to accept the proton after heterolytic splitting of H2.
