5,7-Bis(1-benzothio-phen-2-yl)-2,3-dihydro-thieno[3,4-b][1,4]dioxine.

ABSTRACT: In the title compound, C(22)H(14)O(2)S(3), the dioxane ring is disordered over two sites [site occupancies = 0.623?(3) and 0.377?(3)]; both components adopt half-chair conformations. The two benzothio-phene ring systems are asymmetrically twisted away from the attached thio-phene ring [dihedral angles = 20.57?(3) and 6.70?(3)°] and are oriented at an angle of 26.83?(3)°. No significant hydrogen bonding or ?-? inter-actions are observed in the crystal structure.

Diethyl 2,3-dihydro-thieno[3,4-b]-1,4-dioxine-5,7-dicarboxyl-ate.

Project description:The title compound, C(12)H(14)O(6)S, is a dicarboxylic acid diethyl ester of 3,4-ethyl-enedioxy-thio-phene, which is a component of electrically conductive poly(3,4-ethyl-enedioxy-thio-phene) (PEDOT). The ethyl-ene group is disordered over two sites with occupancy factors 0.64 and 0.36. Both the carbonyl groups are coplanar with the thio-phene ring. The mol-ecules form centrosymmetric dimers with an R(2) (2)(12) coupling by inter-molecular C-H⋯O hydrogen bonds [3.333 (5) Å] at the ethoxy-carbonyl groups. The dimer units are arranged to form a ribbon-like mol-ecular sheet.

Project description:In the title compound, C17H18O5S, an analogue of the potent anti-cancer agent combretastatin A-4, the alkene C=C bond has a cis conformation and the C-C=C-C torsion angle is 9.0 (3)°. The dihedral angle between the benzene and thio-phene rings is 54.07 (4)°. The dioxene ring adopts a half-chair conformation, with the C atoms of the methyl-ene groups displaced by -0.325 (2) and 0.341 (3) Å from the plane of the other atoms. The C atoms of the two meta-meth-oxy groups are close to being coplanar with their attached benzene ring [displacements = -0.025 (2) and -0.196 (2) Å], whereas the C atom of the para-meth-oxy group is significantly displaced [by -1.107 (2) Å]. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into [0-11] chains, which feature two different types of R 2 (2)(6) loops.
