Crystals of 2,4,6-triamino-1,3,5-triazin-1-ium levulinate (4-oxopentanoate) monohydrate, C(3)H(7)N(6)(+).C(5)H(7)O(3)(-).H(2)O, are formed via self-assembled hydrogen bonding by cocrystallization of melamine and levulinic acid. Two N-H.N hydrogen bonds and four N-H.O hydrogen bonds connect two melaminium entities such that each of two pairs of N-H.O bonds bridges two H atoms belonging to the amine groups of two different melaminium cations via the carbonyl O atom of one levulinate molecule.
2,4,6-三氨基-1,3,5-三嗪-1-ium乙酰丙酸酯（4-氧代戊酸酯）一水合物，C(3)H(7)N(6)(+)·C(5)H(7)O(3)(-)·H(2)O的晶体，是通过三聚氰胺和乙酰丙酸共结晶形成的自组装氢键而形成的。两个N-H·N氢键和四个N-H·O氢键连接两个三聚氰胺实体，使得两对N-H·O键中的每一对都通过一个乙酰丙酸酯分子的羰基O原子桥接属于两个不同三聚氰胺阳离子胺基的两个H原子。
