3,3,4,4,5,5-Hexafluoro-1,2-bis-(5-formyl-2-methylsulfanyl-3-thienyl)cyclo-pent-1-ene.

In the crystal structure of the title diaryl-ethyl-ene compound, C(17)H(10)F(6)O(2)S(4), the two 3-thienyl substituents are aligned at 44.9 (1) and 40.2 (1)° with respect to the -C-C=C-C- fragment of the central cyclo-pentenyl ring. The five-membered cyclo-pentenyl ring adopts an envelope conformation. The flap atom of this ring and the two F atoms bonded to it are disordered over two positions with occupancies 0.810 (5)/0.190 (5).
