Probing the Intrinsic Electronic Structure of the Cubane [4Fe-4S] Cluster: Nature's Favorite Cluster for Electron Transfer and Storage

Abstract

The cubane [Fe4S4] is the most common multi-nuclear metal center in nature for electron transfer and storage. Using electrospray, we produce a series of gaseous doubly-charged cubane-type complexes, [Fe4S4L4]2- (L=SC2H5, -SH, -C1, -Br, -I) and the Se-analogs [Fe4Se4L4]-2 L=-SC2H5, -C1), and probe their electronic structures with photoelectron spectroscopy and density functional calculations.
