Diethyl 3,4-bis-(2,5-dimethoxy-benz-yl)thieno[2,3-b]thio-phene-2,5-di-car-boxylate.

ABSTRACT: In the title compound, C(30)H(32)O(8)S(2), the dihedral angle between the two benzene rings is 18.8?(1)°. The mol-ecular structure is stabilized by weak intra-molecular C-H?O hydrogen bonds. In the crystal structure, the mol-ecules are linked via weak inter-molecular C-H?O hydrogen bonds and ?-? inter-actions between two benzene rings [centroid-centroid distance = 3.672?(1)?Å].

In the title compound, C(30)H(32)O(8)S(2), the dihedral angle between the two benzene rings is 18.8 (1)°. The mol-ecular structure is stabilized by weak intra-molecular C-H⋯O hydrogen bonds. In the crystal structure, the mol-ecules are linked via weak inter-molecular C-H⋯O hydrogen bonds and π-π inter-actions between two benzene rings [centroid-centroid distance = 3.672 (1) Å]. ...[more]

Project description:The unique 3,4-ethyl-ene-dioxy-thio-phene (EDOT) unit of the title compound, C(24)H(22)N(2)O(8)S(3)·C(3)H(6)O, is twisted by 1.9 (3)° relative to the central thio-phene ring. The three heterocyclic units are anti-periplanar. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds connect the heterocycles. π-π interactions occur between the central thiophene and the imine bond of the molecule [distance between the ring centroid of the ring and the azomethine bond = 3.413 (3) Å.

Project description:The title compound, C(20)H(18)N(2)O(6)S, crystallizes as two independent mol-ecules that are disposed about a pseudo-inversion center (1/2, 1/4, 1/8). The mean planes of the two terminal furyl rings are twisted with respect to the central thio-phene ring by 7.33 (4) and 21.74 (5)° in one mol-ecule, and by 6.91 (4) and 39.80 (6)° in the other.

2,5-Diamino-thio-phene-3,4-dicarbonitrile.

Project description:In the title compound, C(6)H(4)N(4)S, the planar mol-ecule lies across a crystallographic mirror plane. In the crystal, the mol-ecules form centrosymmetric dimers through cyclic amino N-H⋯N hydrogen-bonding associations with cyano N-atom acceptors [graph set R(2) (2)(12)] and these dimers are extended through amine-cyano N-H⋯N associations into a three-dimensional network.

1,1'-(2,5-Dimethyl-thio-phene-3,4-di-yl)diethanone.

Project description:The title compound, C(10)H(12)O(2)S, crystallizes with four mol-ecules in the asymmetric unit. The main conformational difference between these mol-ecules is the orientation of the acetyl groups with respect to the ring. Whereas one acetyl group is only slightly twisted with respect to the thio-phene ring [C-C-C-O torsion angles = 165.7 (4), -164.6 (4), 164.3 (4) and -163.6 (4)°], the other acetyl group is markly twisted out of the ring plane [C-C-C-O torsion angles = -61.2 (6), 61.3 (7), -59.7 (7) and 59.9 (6)°]. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions into infinite chains along the c axis.

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:The title compound, C(18)H(8)F(6)N(2)O(4)S, is a precursor for the production of low-band-gap conjugated polymers.

The two nitro groups are twisted with respect to the thio-phene ring, the dihedral angles being 53.66?(10) and 31.63?(10)°. Weak inter-molecular C-H?O hydrogen bonding helps to stabilize the crystal structure.
