Abstract

Thermodynamic equations characterizing the chemical stability of heteronuclear diatomic molecules AB are presented. These equations permit one to predict the conditions in which yet unknown molecules can be observed. The chemical stability of the transition element chalcogenides is discussed.
A similarity in trend of the heat of vaporization of transition elements, the lattice energy and the dissociation energy of their chalcogenides is pointed out. AB molecules can be classified in groups for which the vlue of the ratio
α=ΔH°[at.ABsolid]/D° (AB)
is characteristic. This parameter is important for predicting the chemical stability and available values are reviewed.
