A thiolate-bridged ruthenium–molybdenum complex featuring terminal nitrido and bridging amido ligands derived from the N–H and N–N bond cleavage of hydrazine

Abstract

Biomimetic di- or multimetallic complexes featuring NxHy species in a sulfur-rich coordination sphere have attracted considerable attention in modelling the possible scenarios of biological nitrogen fixation by nitrogenases. Although the...

Ammonia synthesis by the reductive N–N bond cleavage of hydrazine using an air-stable, phosphine-free ruthenium catalyst

“…A few bimetallic complexes mimicking the bimetallic cooperativity at the Fe-Mo protein sites of the nitrogenase enzyme have been described for the catalytic hydrazine reduction reaction. [8][9][10] In addition to bimetallic cooperativity, recent catalytic reduction at mononuclear metal centres has also drawn a lot of attention. A mononuclear vanadium or iron core, upon ligation with the thiolate ligands designed by the Hsu group, efficiently reduced hydrazine to ammonia using CoCp 2 and lutidinium salts (LutH + ) as the reductant and proton source (e À /H + ), respectively [Scheme 1b(i)].…”
