Synthetic models of [FeFe]-hydrogenase: case studies utilizing azadithiolate and nitrosyl coligands
… stable when the anion is BArF4-, where adt = (azadithiolate, (SCH2)2NR), R = H and CH2C6H5, BArF4- = tetrakis(bis(3,5-trifluoromethyl)phenyl)borate, and dppv = cis-1,2-bis(diphenylphosphino)ethylene). Solutions of [Fe2(adtR)(CO)3(PMe3)(dppv)]+ react with high pressures of H2 to give the hydride …

Synthesis, spectroscopy, and electrochemistry of hydrogenase mimics
… catalyze the HER via kinetic protonation of an azadithiolate cofactor. Extensive studies of model complexes and hybrid proteins have revealed the importance of the azadithiolate in catalyzing the HER with fast rates. Current synthesis of metal complexes containing azadithiolates gives low yields …

Hydrogen production from model complexes of the [FeFe]- and [NiFe]-hydrogenase active sites
… nickel phosphines led to the impression that an azadithiolate (adt) could function as a proton relay lowering the kinetic barrier of proton transfers to and from the terminal hydride position. Due to the significant amount of steric congestion in [(H)Fe2(pdt)(CO)2(dppv)2]+, the iron hydride does …

Small molecule mimics of hydrogenase enzymes: synthesis, protonation, and electrocatalysis
… (xdt= pdt, 1,2-propanedithiolate, or adtNH= azadithiolate; dppv= cis-1,2-bis(diphenylphosphino)ethylene, which form terminal hydrides that are stable at 0 °C for ~ 30 minutes and then isomerize to the corresponding bridging hydrides. Fe2(adtNH)(CO)4(dppv)2 undergoes protonation with weak …
