(A) H2 activation via side-on binding in a Kubas-type complex, with a terminal cysteine thiolate sulfur acting as the initial proton acceptor during Nia-R formation. (B) Reversible protonation of a Ni-coordinated terminal thiolate ligand has been demonstrated in a bimetallic [NiFe] hydrogenase mimetic compound. (B) Reproduced with permission from ref (100).
