Popis:	The first detection of the phase transition of (ND4)2Se2O5 crystal is reported. The dielectric properties, the deuteron magnetic resonance spectra and the proton spin-lattice relaxation time T1 have been measured. A first-order structural phase transition was found. The ammonium groups play an important role in this transition and change their orientation considerably in the unit cell on going through the transition point.
