The prototype structure of BaMF4 type crystal is considered to be a structure composed of slabs of the perovskite, with the space group D2h17. Normal modes at the Γ point in the orthorhombic Brillouin zone of the hypothetical D2h17 phase and the C2v12 phase below the melting point were analyzed with a help of the group theory. The condensed modes to give the crystal structure at room temperature were assigned and discussed in comparison with the Sr2Ta2O7 structure.
