✦ Synopsis
The crystal structure of ethyl 2-aminooxazole-5-carboxylate, C 6 H 8 N 2 O 3 , consists of planar sheets internally connected by intermolecular hydrogen bonding running parallel to the (120) plane. Interactions between the sheets are limited to dipole± dipole interactions between antiparallel carbonyl groups.
