Rotational distortions due to octahedral tilts and possible ways of successive phase transitions are considered in crystals of TIAIF4-type structure. Crystallographical and group-theoretical analysis of possible transitions from the initial space group D14h was performed. It is shown that in some crystals of the studied type there exist the examples of distortional polytypism, i.e., different types of octahedral tilts in the neighbour layers which have been equivalent in the initial phase.
