Abstract
The title compound, C7H4F3NO2, 3-trifluoromethyl-1H-pyrrolo[1,2-c]oxazol-1-one, is the first crystal structure of the pyrrolo[1,2-c]oxazole ring system: the fused ring system is almost planar (r.m.s. deviation = 0.006 Å). In the crystal, weak C—H⋯O and C—H⋯F hydrogen bonds link the molecules into [001] chains and π–π stacking interactions consolidate the structure.
