Abstract
Ternary Eu pnictides EuTX (T = Ni, Pd, Pt; X = P, As) are mixed valent and undergo one or two first-order phase transitions in dependence of temperature. At the phase transitions the Eu valence changes by about 1/6. The phase transitions are connected with an unusual behaviour of the lattice constants. The observations are explained within a model of electrostatically charged layers.
