      abstract     = {The electronic properties of the ferroelectric compound
                      Sn2P2S6 are investigated by x-ray photoelectron spectroscopy
                      and soft x-ray fluorescence spectroscopy. Excellent
                      agreement between theoretical calculations and experimental
                      data for the electronic structure of the investigated
                      compound is achieved. With help of the Sn core level spectra
                      it is confirmed that the compound contains Sn2+ ions. The
                      valence band mainly consists of five resolvable bands
                      between 3.3 eV and 14.5 eV. Consistent with the results of
                      band-structure calculation and the soft x-ray fluorescence
                      spectra, Sn2P2S6 can be viewed as an ionic crystal, built of
                      Sn2+ and the (P2S6)(4-) fragments. Within the latter, P-P
                      and P-S bonds are largely covalent and characterized by sp
                      hybridization.},
