Аннотация: The structures of three phases of the K3WO3F3 crystal have been determined from X-ray diffraction data obtained for a powder sample. The profile and structural parameters have been refined according to the technique implemented in the DDM program. The results obtained have been discussed using the group-theoretical analysis of the complete order parameter condensate, which takes into account the critical and noncritical atomic displacements and allows the interpretation of the experimental data. The sequence of structural transformations is found to be as follows: Fm (3) over barm 11-10(Gamma(-)(4))->(eta(1), 0, 0) I4mm 11-10(Gamma(-)(4))->(eta(1), eta(2), 0) Cm.
