Abstract
The crystal structure of the title compound, C(29)H(16)F(6)N(2)S(2 center dot)0.5CHCl(3), consists of molecules with disordered perfluorocyclopentene rings [occupancy ratio 0.685 (3):0.315 (3)] and close F center dot center dot center dot F contacts (in the range 2.45-2.73 angstrom) between molecules. The short contacts are associated with the disorder. The dihedral angle between thiophene rings is 57.44 (8)degrees. The 5-( 4- cyanophenyl)-3-methyl-2-thienyl groups of adjacent molecules are parallel, leading to zigzag chains of molecules along [101]. The dihedral angles between each thiophene ring and its adjacent cyanobenzene ring are 8.9 (2) and 7.15 (10)degrees.
