The calculations allowed us to reveal a number of features of the electronic structure, which can cause the manifestation of peculiar structural, magnetic and superconducting properties of these systems. It is demonstrated that the Fermi energy $E_{\\rm F}$ is located close to the pronounced peaks of the electronic density of states (DOS).
