Abstract

The crystal structure of the title compound, C29H16F6N2S2·0.5CHCl3, consists of mol-ecules with disordered perfluoro-cyclo-pentene rings [occupancy ratio 0.685 (3):0.315 (3)] and close F⋯F contacts (in the range 2.45-2.73 Å) between mol-ecules. The short contacts are associated with the disorder. The dihedral angle between thiophene rings is 57.44 (8)°. The 5-(4-cyano-phen-yl)-3-methyl-2-thienyl groups of adjacent mol-ecules are parallel, leading to zigzag chains of mol-ecules along [101]. The dihedral angles between each thiophene ring and its adjacent cyanobenzene ring are 8.9 (2) and 7.15 (10)°.
