Crystal structure of N,N'-[(thio-phene-2,5-di-yl)bis-(methanylyl-idene)]di-p-toluidine.

ABSTRACT: The title compound, C20H18N2S, was synthesized by the condensation reaction between p-tolu-idine and thio-phene-2,5-dicarboxaldehye in refluxing toluene with p-toluene-sulfonic acid added as catalyst. The mol-ecule lies on a twofold rotation axis and adopts an E orientation with respect to the azomethine bonds. The dihedral angle between the unqiue benzene ring and the least-squares plane [maximum deviation = 0.0145?(14)?Å] containing the azomethine and thio-phene groups is 32.31?(6)°.

Project description: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].

Project description:In the crystal structure of the title compound, C(12)H(6)Br(2)S(3), the mol-ecules are planar (r.m.s. deviation = 0.06?Å). Consecutive mol-ecules do not stack in a planar fashion. There is an angle of 81.7?(12)° between the planes of the closest mol-ecules.

Bis(triphenyl-stann-yl) thio-phene-2,5-dicarboxyl-ate.

Project description:Mol-ecules of the title compound, [Sn(2)(C(6)H(5))(6)(C(6)H(2)O(4)S)], lie on inversion centres with the central thio-phene ring disordered equally over two orientations. The carboxyl-ate groups are approximately coplanar with the thio-phene ring [dihedral angle = 4.0?(1)°] and the Sn-O bond distance of 2.058?(4)?Å is comparable to that in related organotin carboxyl-ates.

4,4'-[Thio-phene-2,5-diylbis(ethyne-2,1-di-yl)]dibenzonitrile.

Project description:In the solid state, the title compound, C(22)H(10)N(2)S, forms centrosymmetric dimers by pairs of non-classical C-H?S hydrogen bonds linking approximately coplanar mol-ecules. The benzene ring involved in this inter-action makes a dihedral angle of only 7.21?(16)° with the thio-phene ring, while the other benzene ring is twisted somewhat out of the plane, with a dihedral angle of 39.58?(9)°. The hydrogen-bonded dimers stack on top of each other with an inter-planar spacing of 3.44?Å. C-H?N hydrogen bonds link together stacks that run in approximately perpendicular directions. Each mol-ecule thus inter-acts with 12 adjacent mol-ecules, five of them approaching closer than the sum of the van der Waals radii for the relevant atoms. Optimization of the inter-stack contacts contributes to the non-planarity of the mol-ecule.

Project description:The title compound, C34H40N2O2, exists in an extended conformation and has crystallographically imposed centrosymmetry. The crystal packing can be described as being composed of parallel layers stacked along [010]. The zwitterionic structure is stabilized by an intra-molecular N-H?O hydrogen-bond inter-action.

Project description:The whole mol-ecule of the title compound, C27H26N2O2, is generated by twofold rotational symmetry, with the central C atom of the pentyl chain located on the twofold rotation axis. The compound crystallizes as a bis-zwitterion, and there are two intra-molecular N-H?O hydrogen bonds generating S(6) ring motifs. In the crystal, mol-ecules are linked by pairs of C-H?O hydrogen bonds, forming ribbons propagating along [001], and enclosing R 2 (2)(22) ring motifs.

Project description:The title compound, C22H20Br2N2S, was synthesized under solvent-free conditions. The mol-ecule shows crystallographic C 2 symmetry, with the S atom of the central thio-phene ring lying on a twofold rotation axis.

The dihedral angle between the thio-phene and benzene rings is 72.7?(2)° and that between the two benzene rings is 55.9?(2)°. In the crystal, mol-ecules are arranged in a chevron-like pattern, without any significant inter-molecular inter-actions.
