Abstract: | The crystals of a new melaminium salt, 2,4,6‐triamino‐1,3,5‐triazine‐1,3‐diium bis(4‐hydroxybenzenesulfonate) dihydrate, C3H8N62+·2C6H5O4S?·2H2O, are built up from doubly protonated melaminium(2+) residues, dissociated p‐phenolsulfonate anions and water molecules. The doubly protonated melaminium dication lies on a twofold axis. The hydroxyl group of the p‐hydroxybenzenesulfonate residue is roughly coplanar with the phenyl ring dihedral angle 13 (2)°]. A combination of ionic and donor–acceptor hydrogen‐bond interactions link the melaminium and p‐hydroxybenzenesulfonate residues and the water molecules to form a three‐dimensional network. |
