Energy structure of the valence band of the Ce2ScSi2 and СеScSi compounds was studied by the methods of the high-energy spectroscopy (XPS, XES and XAS). Dependence of magnetic susceptibility χ(Т) of the Ce2ScSi2 compound within wide temperature range corresponds to the Curie-Weiss law. Based upon temperature dependences χ(Т) and α(Т), together with calculated valence of Ce by the data of the absorption LІІІ –spectroscopy, a conclusion has been made on the existence of the fluctuating transition, «State of intermediate valence - Condo-systems", in the Ce2ScSi2 compound. The calculations of electron energy bands E(k) and partial DOS for Ce2ScSi2 and СеScSi compounds were performed by the semi relativistic linear muffin-tin orbital method without considerations of spin-orbit interactions A satisfactory agreement between theoretical and experimental data is achieved.
