4-(5-{2-[5-(4-Cyano­phen­yl)-3-methyl­thio­phen-2-yl]-3,3,4,4,5,5-hexa­fluoro­cyclo­pent-1-en-1-yl}-4-methyl­thio­phen-2-yl)benzo­nitrile chloro­form hemisolvate

Abstract: The crystal structure of the title compound, C29H16F6N2S2·0.5CHCl3, consists of mol­ecules with disordered perfluoro­cyclo­pentene rings [occupancy ratio 0.685 (3):0.315 (3)] and close F...F contacts (in the range 2.45-2.73 Å) between mol­ecules. The short contacts are associated with the disorder. The dihedral angle between thiophene rings is 57.44 (8)°. 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)°.
