Allyl­ammonium hydrogen oxalate hemihydrate

In the title hydrated mol­ecular salt, C(3)H(8)N(+)·C(2)HO(4) (−)·0.5H(2)O, the water O atom lies on a crystallographic twofold axis. The C=C—C—N torsion angle in the cation is 2.8 (3)° and the dihedral angle between the CO(2) and CO(2)H planes in the anion is 1.0 (4)°. In the crystal, the hydrogen...

Sumario:In the title hydrated mol­ecular salt, C(3)H(8)N(+)·C(2)HO(4) (−)·0.5H(2)O, the water O atom lies on a crystallographic twofold axis. The C=C—C—N torsion angle in the cation is 2.8 (3)° and the dihedral angle between the CO(2) and CO(2)H planes in the anion is 1.0 (4)°. In the crystal, the hydrogen oxalate ions are linked by O—H⋯O hydrogen bonds, generating [010] chains. The allyl­ammonium cations bond to the chains through N—H⋯O and N—H⋯(O,O) hydrogen bonds. The water mol­ecule accepts two N—H⋯O hydrogen bonds and makes two O—H⋯O hydrogen bonds. Together, the hydrogen bonds generate (100) sheets.
