3-Methoxy-3-oxopropanaminium chloride

In the title compound, C4H10NO2+·Cl , the central ethylene bond of the cation adopts a gauche conformation. The three H atoms of the –NH3+ group are engaged in strong and highly directional intermolecular N—H...Cl hydrogen bonds, which result in a tape-like arrangement along [010] of the respective ion pairs. In addition, weak intermolecular C—H...Cl and C—H...O interactions are present.
