Crystal structure of the high-pressure phase in (CH_3)_2NH_2H_2PO_4 was analyzed using X-ray diffraction data measured at p ≅ 1.2GPa and T = 295(1)K. Lattice constants a = 9.057Å, a = 9.468Å, c = 6.822Å, α = 93.25°, space group P2_1/b11, Z = 4. Though half of PO_4 groups rotate by 50° through pressure-induced phase transition, hydrogen bonded chain structure of PO_4 along the b- and c-axes is preserved.
