The asymmetric unit of the title compound, C 9 H 9 N 3 O 4 , consists of two independent but similar molecules which are located on mirror planes. The molecules pack along the b axis with an interplanar distance of b/2. Intramolecular N-HÁ Á ÁO hydrogen bonds help to stablize the molecular structure

The title compound, C 9 H 8 N 2 O 3 , was obtained by a zinc chloride-promoted addition and ring-closure reaction involving 3-nitrobenzonitrile and 2-ethanolamine. The planar oxazoline and aromatic rings of the molecule are almost coplanar, with a dihedral angle of 8.79 (5) between them. The oxazoli
