Abstract: In the title compound, C4H8N5+·Cl-, a two-dimensional layer packing network is observed in which every chloride anion links three adjacent 2,4-diamino-6-methyl-1,3,5-triazin-1-ium cations by N-HCl hydrogen-bonding interactions, forming 12-membered and eight-membered hydrogen-bonded rings with graph-set motifs R44(12) and R33(8), respectively. In addition, N-HN hydrogen bonds are found between adjacent cations, forming another type of eight-membered [R22(8)] hydrogen-bonded ring.
