3,3,4,4,5,5-Hexafluoro-1,2-bis(5-formyl-2-methylsulfanyl-3-thienyl)cyclopent-1-ene
In the crystal structure of the title diaryl-ethyl-ene compound, C(17)H(10)F(6)O(2)S(4), the two 3-thienyl substituents are aligned at 44.9 (1) and 40.2 (1)° with respect to the -C-C=C-C- fragment of the central cyclo-pentenyl ring. The five-membered cyclo-pentenyl ring adopts an envelope conformation. The flap atom of this ring and the two F atoms bonded to it are disordered over two positions...
متن کامل3-(4-{3,3,4,4,5,5-Hexafluoro-2-[5-(3-methoxyphenyl)-2-methyl-3-thienyl]cyclopent-1-enyl}-5-methyl-2-thienyl)benzonitrile
The title compound, C(29)H(19)F(6)NOS(2), is a new unsymmetrical photochromic diarylethene derivative with different meta-phenyl substituents. The distance between the two reactive (i.e. can be irradiated to form a new chemical bond) C atoms is 3.501 (4) Å; the dihedral angles between the mean plane of the main central cyclo-pentene ring and the thio-phene rings are 47.7 (5) and 45.1 (2)°, and ...
متن کامل1-[5-(3-Chlorophenyl)-2-methyl-3-thienyl]-3,3,4,4,5,5-hexafluoro-2-(2-methoxyphenyl)cyclopent-1-ene
The title compound, C(23)H(15)ClF(6)OS, has thienyl and phenyl-ene substituents on the double-bond C atoms of the envelope-shaped cyclo-pentenyl ring. The aromatic systems are aligned at 55.3 (4) (thien-yl) and 60.8 (7)° (phenyl-ene) with respect to the planar C-C=C-C portion of the main central cyclo-pentenyl ring.
متن کامل3-Methyl-5α-cholest-2-ene
In the title cholestane derivative, C(28)H(48) [systematic name: (1S,2S,7R,10R,11R,14R,15R)-2,5,10,15-tetra-methyl-14-[(2R)-6-methyl-heptan-2-yl]tetra-cyclo-[8.7.0.0(2,7).0(11,15)]hepta-dec-4-ene], the cyclo-hexene ring adopts a half-chair conformation. The parent 5α-cholest-2-ene and the equivalent fragment of the title compound are almost superimposable (r.m.s. deviation = 0.033 Å).
متن کاملCrystal structure of 3-[(E)-(2-hydroxy-3-methoxybenzylidene)amino]-1-methyl-1-phenylthiourea
In the asymmetric unit of the title compound, C16H17N3O2S, there are two independent mol-ecules (A and B), which show an E conformation with respect to the C=N bond. An intra-molecular O-H⋯N hydrogen bond with an S(6) motif stabilizes the mol-ecular structure. The terminal phenyl and benzene rings are almost orthogonal to each other, the dihedral angle being 87.47 (13)° for mol-ecule A and 89.8...
