Abstract Mixed alkali hexafluorotitanates of the composition LiMTiF6 are synthesized, which crystallize with the orthorhombic symmetry. The lattice parameters of these materials are determined. It is shown that substitution of the Li+ cation in Li2TiF6 by Na+, K+, Rb+, and Cs+ leads to various degrees of distortion of the hexafluoroion. It is determined (19F NMR data) that the change in the dynamic state of the octahedral [TiF6]2− ions is related to their transition from the hindered-rotational to the isotropic state.
