摘要：

Some results of calorimetric and structural investigations of the A(2)A'MOxF6-x crystals series with the elpasolite-cryolite structure are reported. The analysis has exhibited a key role of the MOxF6-x species content in the disordering degree and stability of Fm(3)m phase as well as in the nature of structural distortions.
