Bimetallic carbonyl thiolates as functional models for Fe-only hydrogenases

Research has been conducted on mixed ligand species [Fe (sub)2 -(S (sub)2 C (sub)3 H (sub)6)(CN)(CO) (sub)4 (PMe (sub)3)] (super)- which catalyzes proton electroreduction to dihydrogen. The description of this compound and its derivatives and analogues as they relate to the proton reduction process, analyzed theoretically and electrochemically, is presented.
