Аннотация: Oxyfluoride (NH4)(2)WO2F4 has been studied by the inelastic neutron scattering method over a wide temperature range 10-300 K at two initial neutron energies of 15 and 60 meV. The role of tetrahedral ammonium groups in the mechanism of sequential phase transitions at T (1) = 201 K and T (2) = 160 K has been discussed.
