Metal vs. ligand protonation and the alleged proton-shuttling role of the azadithiolate ligand in catalytic H₂ formation with FeFe hydrogenase model complexes.

ABSTRACT: Electron and proton transfer reactions of diiron complexes [Fe₂adt(CO)₆] (1) and [Fe₂adt(CO)₄(PMe₃)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 potential proton shuttle in catalytic H₂ formation. Protonation of the one-electron reduced complex, 1^- , occurs on the adt-N yielding 1H and the same species is obtained by one-electron reduction of 1H⁺ . The preference for ligand vs. metal protonation in the Fe₂(i,0) state is presumably kinetic but no evidence for tautomerization of 1H to the hydride 1H
