We used photoelectron spectroscopy (PES) to study how the terminal ligands influence the electronic structure and redox properties of the [4Fe-4S] cubane in several series of ligand-substituted analogue complexes: [Fe4S4CI4-x(CN)x]2-, [Fe4S4CI4-x(SCN)x]2-, [Fe4S4CI4-x(OAc)x]2-, [Fe4S4(SC2H5)4-x(OPr)x]2-, and [Fe4S4(SC2H5)4-x(CI)x]2-(x=0-4). All the ligand-substituted complexes gave similar PES spectra as the parents, suggesting that the mixed-ligand coordination does not perturb the electronic structure of the cubane core significantly.
