Metal vs. ligand protonation and the alleged proton-shuttling role of the azadithiolate ligand in catalytic H(2) formation with FeFe hydrogenase model complexes

Electron and proton transfer reactions of diiron complexes [Fe(2)adt(CO)(6)] (1) and [Fe(2)adt(CO)(4)(PMe(3))(2)] (4), with the biomimetic azadithiolate (adt) bridging ligand, have been investigated by real-time IR- and UV-vis-spectroscopic observation to elucidate the role of the adt-N as a potenti...
