A phenomenological approach for construction theoretical phase diagrams with multiple phase transitions including incommensurate transitions is developed for the case when a special triple point, a Lifshitz-type point, is assumed to be present in the experimental diagram for ｛N(CH_3)_4｝_2ZnCl_4 crystal family. The theoretical temperature-pressure phase diagram for ｛N(CH_3)_4｝_2ZnCl_4 is plotted and is found to be in agreement with the experimental phase diagram. The approximations and assumptions made in the construction of the diagrams are discussed.
