Abstract
In the title compound, C(12)H(8)F(2)O(2)S, which is a precursor of functionalised poly(aryl-ene ether sulfone) polymers, the dihedral angle between the aromatic ring planes is 84.43 (8)°. In the crystal structure, aromatic π-π stacking [centroid-centroid separations = 3.808 (3) and 3.867 (3) Å] helps to establish the packing. A short C-H⋯F contact also occurs.
