Abstract
The title compound, C(7)H(4)F(3)NO(2),
3-tri-fluoro-methyl-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 mol-ecules into [001] chains and π-π stacking inter-actions consolidate the
structure.
