Chemical preparation, X-ray single-crystal, thermal behavior, and IR spectroscopy investigations are given for a new organic cation dihydrogenomonophosphate (C₇H₉N₂O)H₂PO₄ (denoted ABHP) in the solid state. This compound crystallizes in the monoclinic space group P2₁/n. The unit cell dimensions are: a = 11.011(5) Å, b = 5.861(1) Å, c = 15.944(4) Å and β = 100.81(5) with V = 1010.7(6) ų and Z = 4. The structure has been solved using direct method and refined to a reliability R factor of 0.048. The atomic arrangement can be described as inorganic clusters [H₄P₂O₈]^2- anions between which are located the organic dimmers (C₁₄H₁₈N₄O₂)²⁺ through multiple hydrogen bonds (Figure 1)
