Project description:The title compound, C(22)H(13)ClF(6)S, is a hybrid diaryl-ethene derivative with one 3-thienyl substituent, and a Cl-substituted six-membered aryl unit bonded to the double bond of a hexa-fluoro-cyclo-pentene ring.

The distance of 3.612?(3)?Å between the potentially reactive C atoms of the two heteroaryl substituents is short enough to enable a photocyclization reaction.

Project description: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)°.

5-n-Butyl-4-[2-(2-ethyl-1-benzothio-phen-3-yl)-3,3,4,4,5,5-hexa-fluoro-cyclo-pent-1-en-1-yl]thio-phene-2-carbaldehyde.

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. The mean planes of aromatic systems form dihedral angles of 43.0 (1) (thien-yl) and 73.8 (1)° (benzothien-yl) with the mean plane of the C-C=C-C portion of the cyclo-pentene ring. This conformation avoids steric hindrance between the n-butyl and ethyl substituents. The formyl substituent of the thienyl group, as well as the ethyl substituent of the benzothienyl group, are disordered [occupancies of 0.788 (17):0.212 (17) and 0.64 (5):0.36 (5), respectively].

3-(4-Bromo-phen-yl)cyclo-pent-2-en-1-one.

Project description:In the title compound, C11H9BrO, the cyclo-pentenone ring is almost planar with an r.m.s. deviation of 0.0097?Å. The largest inter-ring torsion angles [2.4?(3), 1.3?(3) and 3.53?(2)°] reveal only a very small twist between the rings, and suggest that the two rings are conjugated. The mol-ecule is slightly bowed, as shown by the small dihedral angle between the rings [5.3?(1)°]. The crystal packing pattern consists of parallel sheets that stack parallel to the ac plane. Each sheet consists of mol-ecules that pack side-to-side with the same relative orientation of phenyl and cyclo-pentenone rings along the a- and c-axis directions. Slipped side-to-side, face-to-face and edge-to-face inter-actions exist between pairs of sheets with edge-to-edge and edge-to-face O?H-C(sp (2)) weak hydrogen-bond contacts. A relatively short edge-to-face contact (2.77?Å) also exists between pairs of sheets.

Project description:The title compound, C(29)H(23)F(6)NO(2)S, a member of a new family of photochromic diaryl-ethene compounds having an unsymmetrically substituted hexa-fluoro-cyclo-pentene unit, displays dihedral angles between the indole and thio-phene rings of 52.5?(4)°, and between the indole ring and the planar C-C=C-C unit of the cyclopentene ring of 53.8?(6)°. The distance between the potentially reactive C atoms from the two heteroaryl substituents of 3.817?(6)?Å is proven to be short enough for photocyclization to occur.
