In the title methanol-solvated salt, C14H19Cl3N5O2+·Cl-·-CH3OH, the triazine molecule is protonated at one of the triazine N atoms. In the crystal, the triazine cations are linked through a pair of N-H··· N hydrogen bonds, with graph-set R22(8), forming an inversion dimer. The protonated N atom and the 2- and 4-amino groups of the triazine cation interact with the chloride anion through N-H···Cl hydrogen bonds, leading to the formation of a tape structure running along the b-axis direction. A short Cl···Cl contact [3.2937 (9) Å] is observed in the tape. The methanol molecule is linked to the chloride anion and the triazine cation, respectively, by an O-H···Cl hydrogen bond and a C-H···O interaction.
