Modeling the active site of [FeFe]-hydrogenase : Electro-catalytic hydrogen evolution from acetic acid catalysed by [Fe 2 (μ-L)(CO) 6 ] and [Fe 2 (μ-L)(CO) 5 (PPh 3 )] (L=pyrazine-2,3-dithiolate, quinoxaline-2,3-dithiolate and pyrido[2,3-b]pyrazine-2,3-dithiolate) / created by - Journal of chemical sciences Volume 127, number 2, .
Compounds [Fe2(CO)6] (pydt = pyrazine-2,3-dithiolate) (1), [Fe2(CO)6] (qdt = quinoxaline-2,3-dithiolate) (2), [Fe2(CO)6] (ppdt = pyrido[2,3-b]pyrazine-2,3-dithiolate) (3), [Fe2 (CO)5PPh3] (4), [Fe2(CO)5PPh3] (5) and [Fe2(CO)5PPh3] (6) have been synthesized in order to model the active sites of ‘[FeFe]-hydrogenase’. Compounds 1–6 have been characterized by routine spectral studies and unambiguously by single crystal X-ray crystallography. Supramolecular chemistry of compounds 1–6 have been described in terms of intermolecular interactions, observed in their respective crystal structures. Electro-catalytic hydrogen evaluation studies (from acetic acid) have been performed using compounds 1–6 as electro-catalysts. The mechanistic aspects of relevant electro–catalytic proton reductions have been discussed in detail.
