Electric conductivity and X-ray diffraction measurements are performed on deuterated triammonium hydrogen disulphate (ND ) D(SO ) in high temperature phase. A new structural phase transition that corresponds to the transition at 463 K of 4 3 4 2 (NH ) H(SO ) is found at 413 K. The space group symmet
