Enthalpy stabilization of complex coordination oxides and coherent growing together phases in perovskite like compounds

Formation enthalpies of complex coordination oxides of transition and alkaline earth metals of diverse structural types, including the phases of accretion with fragments of perovskite-like compounds, were calculated by approximated methods of calculation using enthalpies of changes in coordination numbers of cations in the course of forming structures from simple oxides. Thermochemical (enthalpy) stabilization of the compounds in most cases is brought about by exoeffects in the change of strontium, barium and lanthanum ion coordination numbers
