The electronic structure of the polynuclear iron carbonyl complexes [Et2N][Fe4N(CO)12], [Et4N]2[Fe5C(CO)14], and [Et4N]2[Fe6C(CO)16] has been studied by X-ray emission spectroscopy and quantum-chemical calculations. The fine structure of the FeKβ5 X-ray emission spectra characterizes the distribution of iron valence p electrons over the molecular orbitals of the compounds. Comparison of the fine structure of the FeKβ5 X-ray emission spectra with the densities of states of all atoms in the molecules has made it possible to determine in detail the character and specific features of chemical bonding in the complexes.
