Abstract
The title compound, C11H9F3O5, crystallizes with three molecules in the asymmetric unit. One –CF3 group is disordered by rotation, with the F atoms split over two sets of sites with occupancies which converged to 0.888 (6) and 0.112 (6). Weak π–π interactions are observed between adjacent benzene rings [the shortest centroid–centroid distance is 3.8858 (4) Å], resulting in the formation of a supramolecular chain along [100].
