Resumen en inglés

Orientationally disordered stable and metastable mixed crystals of the two-component system 2,2-dichloropropane ((CH3)2CCl2)+carbon tetrachloride (CCl4) have been characterised from crystallographic and thermodynamic points of view. The monotropic behaviour of the metastable phases in the pure components is retained by the mixed crystals. Continuous series of mixed crystals in the stable rhombohedral phase gives rise to an isomorphism relationship. The lattice symmetries of the metastable mixed crystals are found to be simple cubic and face centred cubic, the latter corresponding to a large concentration domain. A strong correlation between thermodynamic functions and optical properties is proposed.< Leer menos
