6-Meth-oxy-meth-oxy-7-trifluoro-methyl-1,3-benzodioxole-5-carbaldehyde.
The title compound, C(11)H(9)F(3)O(5), crystallizes with three mol-ecules in the asymmetric unit. One -CF(3) 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 inter-actions are observed between adjacent benzene rings [the shortest centroid-centroid distance is 3.8858 (4) Å], resulting in the formation of a supra-molecular chain along [100].
