4-(5-{2-[5-(4-Cyano-phen-yl)-3-methyl-thio-phen-2-yl]-3,3,4,4,5,5-hexa-fluoro-cyclo-pent-1-en-1-yl}-4-methyl-thio-phen-2-yl)benzo-nitrile chloro-form hemisolvate.

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)°.

Project description:The title compound, C(43)H(32)F(6)N(2)S(2), is a new symmetrical photochromic diaryl-ethene derivative with 9-ethyl-carbazol-3-yl substituents. The mol-ecule adopts a photoactive anti-parallel conformation [Irie (2000). Chem. Rev.100, 1685-1716; Kobatake et al. (2002). Chem. Commun. pp. 2804-2805], with a dihedral angle between the mean planes of the two thio-phene rings of 56.23?(6)°. The distance between the two reactive C atoms is 3.497?(3)?Å. In the crystal, two mol-ecules are associated through a pair of C-H?F inter-molecular hydrogen bonds, forming a centrosymmetric dimer. Dimers are linked by weak ?-? inter-actions [centroid-centroid distance = 3.8872?(13)?Å], forming chains along the c axis.

Project description:The title compound, C(24)H(20)F(6)OS(2), exhibiting photochromic behaviour, has thienyl and benzothienyl substituents attached to the double-bond C atoms of the envelope-shaped cyclo-pentene ring.
