2,4,6-Tri­amino-1,3,5-triazin-1-ium 3-(prop-2-eno­yloxy)propano­ate acrylic acid monosolvate monohydrate

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—H...N and N—H...O hydrogen bonding. The crystal studied was a non-merohedral twin, the minor component contribution being approximately 26%.
