Sulfur‐Rich μ‐O Diiron Catalyst for Electrochemical Hydrogen Production
European Journal of Inorganic Chemistry, Volume 29, Issue 8, 10 March 2026.A diferric μ‐oxido complex supported by a sulfur‐rich scaffold acts as a proton‐reduction electrocatalyst for H2 production via a μ‐hydroxido species. An aminodithiophenolate scaffold with an NS2 donor set supports diiron complex formation. The diferrous precursor activates O2, giving rise to a diferric μ‐oxido species, which acts as a proton‐reduction
