Abstract
The title compound, C10H13N2O4 +·Cl−, comprises a Cl− anion and a protonated aminium cation. The crystal packing is stabilized by cation–anion N—H⋯Cl hydrogen bonds and N—H⋯O hydrogen bonds, building an infinite two-dimensional network parallel to the (001) plane. The S absolute configuration at the chiral center was deduced from the synthetic pathway and confirmed by the X-ray analysis.
