Abstract The paper presents the influence of deuteration of (NH4)4LiH3(SeO4)4 single crystal on its ferroelastic properties. A considerable negative isotopic effect ΔT = 9 K has been found. It is supposed that hydrogen bonds significantly influence phase transitions in Me4LiH3(XO4)4 single crystals.
