On the basis of dilatometric, optical, and dielectric investigations of (NH_{3}C_{2}H_{5})_{2}CuCl_{4} crystals the existence of phase transitions at T_{1}=364 and T_{2}=356 K was confirmed. Anomalous behaviour of the thermal expansion coefficient and optical birefringence around T_{3}=330 K was related to earlier unknown phase transition. Besides, it was shown that these crystals are characterised by considerable protonic conductivity, the nature of which is fairly well explained in the framework of Grotthus mechanism of proton transport.
