Molecular models for polymorphic modifications of zinc selenide have been designed. Based on the results of quantum-chemical calculations of the structure and properties of clusters, the enthalpy of formation and Gibbs energy of the sphalerite- and wurtzite-type modifications have been computed, and the temperature for the phase transformation “sphalerite-wurtzite” estimated.
