Synthesis, Crystal Structure and Characterization of a New Dihydrogenomonophosphate: (C7H9N2O)H2PO4


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) Å3 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)
