H.-F. Qian and W. Huang

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.
