Base metal, mol. catalysts for the fundamental process of conversion of protons and electrons to dihydrogen remain a substantial synthetic goal related to a sustainable energy future. A novel approach has produced a diiron complex with bridging thiolates in the butterfly shape of the 2Fe2S core of the [FeFe]-hydrogenase active site, but with NO rather than CO or CN- ligands, that is demonstrated to maintain structural integrity in two redox levels. Various spectroscopies corroborate the roles of the iron centers in electrocatalytic proton redn. The binuclear [(NO)Fe(N2
