A neutron diffraction study of temperature induced phase transition in Rb2KFeF6 elpasolite has been performed. At room temperature the structure is cubic with space group Fm3m. At T = 170 K a structural phase transition takes place. Space group and atom coordinates in this phase has been defined. The crystal structure is good refined by orthorhombic space group Pmnn. Possible models are discussed.< Leer menos
