Abstract The influence of deuteration of (NH4)LiH3(SeO4)4 single crystal on its ferroelastic properties is presented. A negative isotopic effect |δT| = 8 K has been found. The significant influence of hydrogen bonds on ferroelastic phase transition in A4LiH3(XO4)4, X = S, Se family of crystal was confirmed.
