The temperature dependences of birefringence in thin [N(CH3)(4)](2)Zn0.58Cu0.42Cl4 crystals in the thickness range 20 x 10(-6) a parts per thousand currency sign d a parts per thousand currency sign 500 a dagger 3/4 10(-6) m have been investigated. An increase in the temperatures of the parent phase-incommensurate phase and incommensurate phase-ferroelectric phase transitions has been found. The reasons for the shift in the phase transition temperatures with a decrease in the thickness of [N(CH3)(4)](2)Zn0.58Cu0.42Cl4 crystal and the size effect in crystals with an incommensurate superstructure are discussed.
