Abstract Dielectric investigations of the one-layer perovskite-like crystal Bi2TiO4F2 were carried out. It was shown that this material is ferroelectric with the Curie temperature Tc =11°C ± 0.5°C. The ferroelectric phase transition is accompanied by the change of unit cell symmetry C 20 2ν-Imm2 to D 4h-I4/mmm.
