SW Xα calculations and x-ray photoelectron spectra of molybdenum(II) chloride cluster compounds

X-ray photoelectron spectra of the [Mo6Cl8]Cl4 cluster compound have been measured and discussed. For the interpretation of the valence band spectrum several SW Xα calculations have been performed. Comparison between calculated and experimental spectra illustrates the importance of covalent Mo-Cł bonding for the stability of the cluster.
