An aminodithiophenolate scaffold with an NS 2 donor set supports diiron complex formation. The diferrous precursor activates O 2 , giving rise to a diferric μ‐oxido species, which acts as a proton‐reduction electrocatalyst for H 2 production at diiron sites relevant to hydrogenase enzymes.
Hernández‐Toledo et al. (Fri,) studied this question.
