Abstract: In the title compound, 2C₁₇H₁₉N₂⁺·2H₂PO₄^-·3H₃PO₄·CH₃OH, Tröger base, phosphoric acid and methanol are included in the crystal structure, the asymmetric unit of which contains three protonated acid units. The structure includes hydrophilic layers of dihydrogen phosphate anions, phosphoric acid and methanol which are interconnected by O-HO hydrogen bonds. These layers alternate with the more hydrophobic Tröger base. Each Tröger base acts as a proton donor in an N-HO hydrogen bond.
