Synthetic azadithiolate-bridged diiron clusters serve as structural analogues of the active site [FeFe]-hydrogenases. Recently, an o-alkyl substitution aniline-based azadithiolate bridge allowed these synthetic models to both oxidize H2 and reduce H+, i.e., bidirectional catalysis. Hydrogen oxidation by hydrogenases is rare, even rarer ability hexacarbonyls H2. A series biomimetic hexacarbonyl complexes are synthesized where in para position ortho-methyl aniline systematically varied between electron-withdrawing electron-donating groups understand factors that control The results show substituents ortho-ethyl affect electronic structure well cluster. −NO2 substituent faster relative a −OCH3 substituent.
