Ultrafast Photodynamics of Cyano-Functionalized [FeFe] Hydrogenase Model Compounds.

ABSTRACT: [FeFe] hydrogenases are efficient enzymes that produce hydrogen gas under mild conditions. Synthetic model compounds containing all CO or mixed CO/PMe₃ ligands were previously studied by us and others with ultrafast ultraviolet or visible pump-infrared probe spectroscopy in an effort to better understand the function and interactions of the active site with light. Studies of anionic species containing cyano groups, which more closely match the biological active site, have been elusive. In this work, two model compounds dissolved in room-temperature acetonitrile solution were examined: [Fe₂(μ-S₂C₃H₆)(CO)₄(CN)₂]^2- (1) and [Fe₂(μ-S₂C₂H₄)(CO)₄(CN)₂
