The crystals of a new melaminium salt, bis(2,4,6-triamino-1,3,5-triazin-1-ium) sulfate dihydrate, 2C3H7N6+*SO4(2-)*2H2O, are built up from monoprotonated melaminium(1+) residues, sulfate(2-) anions and water molecules. The SO4(2-) ion has a slightly distorted tetrahedral geometry. The melaminium residues are interconnected by N-H.N hydrogen bonds, forming chains. The chains of melaminium residues develop a three-dimensional network through multiple donor-acceptor hydrogen-bond interactions with sulfate anions and water molecules.
一种新型三聚氰胺盐二水合硫酸双（2,4,6 - 三氨基 - 1,3,5 - 三嗪 - 1 - 鎓），即2C₃H₇N₆⁺·SO₄²⁻·2H₂O，其晶体由单质子化的三聚氰胺（1⁺）残基、硫酸根（2⁻）阴离子和水分子构成。SO₄²⁻离子具有略微扭曲的四面体几何构型。三聚氰胺残基通过N - H···N氢键相互连接，形成链状结构。三聚氰胺残基链通过与硫酸根阴离子和水分子的多重供体 - 受体氢键相互作用形成三维网络。
