Abstract
In the title compound, C12H11N3O3, the dihedral angle between the 3-nitrobenzaldehyde and 5-amino-3,4-dimethyl-1,2-oxazole moieties is 2.46 (12)degrees. The molecule is close to planar, the r.m.s. deviation for the non-H atoms being 0.028 angstrom. The packing only features van der Waals interactions between the molecules.
