In the title hydrated salt, 2,4,6-triamino-1,3,5-triazin-1-ium perchlorate monohydrate, C3H7N6+·ClO4-·H2O, the constituents are linked via hydrogen bonds of the O-HO, N-HO, N-HN and N-HCl types. All the H atoms of the melaminium cation are involved in the hydrogen bonds. The melaminium residues are interconnected by four N-HN hydrogen bonds, forming chains parallel to (111). The ribbons are interconnected by other hydrogen bonds as well as by - interactions [centroid-centroid distance = 3.8097 (7) Å].
