Abstract: In the title compound, C₁₇H₁₀F₆O₄S₂·0.25C₃H₆O, there are two non-solvent molecules in the asymmetric unit, with different conformations. One is a photo-active antiparallel conformation in which the reactive C atoms are separated by 3.569 (6) Å. The other is a photo-inactive parallel conformation in which the reactive C atoms are separated by 4.541 (7) Å.
