The asymmetric unit of the title salt, C3H7N6+·C6H7O4−·C3H4O2·H2O, contains a 2,4,6-triamino-1,3,5-triazin-1-ium cation, a 3-(prop-2-enoyloxy)propanoate anion and acrylic acid and water solvent molecules in a 1:1:1:1 ratio and with each species in a general position. In the crystal, the components are linked into a supramolecular layer in the bc plane via a combination of O—H
O, N—HN and N—HO hydrogen bonding. The crystal studied was a non-merohedral twin, the minor component contribution being approximately 26%.

The asymmetric unit of the title compound, C3H6N6·2C6H5NO3, contains one melamine and two 3-nitrophenol molecules. The mean planes of the 3-nitrophenol molecules are almost orthogonal to the plane of melamine, making dihedral angles of 82.77 (4) and 88.36 (5)°. In the crystal, molecules are linked via O—HN, N—HN and N—HO hydrogen bonds, forming a three-dimensional network. The crystal also features weak C—Hπ and π–π interactions [centroid–centroid distance = 3.9823 (9) Å].
