In the title compound, C 5 H 14 N 2 O 2 2+ ÁSO 4 2À ÁH 2 O, the ornithinium cation forms a strong OÐHÁ Á ÁO hydrogen bond with the sulfate anion. One backbone conformation angle is in an eclipsed conformation, while the other two are in a trans±trans staggered conformation. All the amino and carboxy
