Abstract Raman spectra and rotation angle of the indicatrix have been measured in the intermediate phase of the crystal [N(CH3)4]2Znl4 The results are consistent with the existence of large ferroelastric domains piled up along the a axis in a monoclinic phase P1121/a (Pnma notation in the paraelectric phase). The phase sequence (Pnma-P1121/a-P21ca) in this compound is different from other members of [N(CH3)4]2BX4 family.
