*d*-electrons in the mixed-valence phenomena has been investigated. Falicov-Kimball model extended by NNN hopping has been considered. Calculations have been made both at zero and at finite temperatures. It has been observed that NNN hopping (i) shifts the

*d*-level energy, (ii) makes the system more disordered, (iii) decreases degeneracy of the ground...
