Diethyl 3,4-dimethyl-thieno[2,3-b]thio-phene-2,5-dicarboxyl-ate.

Project description:In the title compound, C14H16O4S2, the thieno[2,3-b]thio-phene ring systems are planar [maximum deviation = 0.008 (2) Å]. The mol-ecular conformation is stabilized by intra-molecular C-H⋯O hydrogen bonds, while the crystal packing is stabilized by C-H⋯O, C-H⋯π and π-π stacking [centroid-centroid distance = 3.6605 (14) Å] inter-actions, which lead to supra-molecular layers in the ab plane.

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, C(24)H(24)N(2)O(2), the five-membered ring of the indoline ring system adopts an envelope conformation with the spiro C atom at the flap. The dihedral angle between the benzene ring of the indoline ring system and the naphthalene ring system is 71.70 (7)°. In the crystal structure, pair of weak C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.

Diethyl indolizine-1,3-dicarboxyl-ate.

Project description:The title compound, C(14)H(15)NO(4), was prepared by a 1,3-dipolar cyclo-addition from N-(eth-oxy-carbonyl-methy)pyridinium bromide and ethyl acrylate. The -CO(2) side chains form dihedral angles of 0.2 (3) and 2.4 (3)° with respect to the ring system. In the crystal, two neighbouring mol-ecules form a dimer through weak C-H⋯O interactions. The dimers form a three-dimensional structure via further weak C-H⋯O inter-actions.

The mol-ecular structure is stabilized by weak intra-molecular C-H⋯O inter-actions and the crystal structure is stabilized through weak inter-molecular C-H⋯O inter-actions.
