2-Amino-4-methyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile.

ABSTRACT: In the title compound, C(10)H(12)N(2)S, the thio-phene ring is essentially planar (r.m.s. deviation = 0.0290?Å). The two C atoms of the cyclo-hexene ring (at positions 6 and 7) are disordered over two sets of sites in a 0.810?(5):0.190?(5) ratio. The cyclo-hexene rings in both the major and minor occupancy conformers adopt a half-chair conformation. In the crystal, there are two types of N-H?N inter-action. One of these results in centrosymmetric head-to-head dimers corresponding to an R(2) (2)(12) graph-set motif and the other forms a 20-membered macrocyclic ring involving six mol-ecules.

Project description:In the title compound, C(10)H(12)N(2)S, one of the C atoms of the cyclo-hexene ring (at position 6) and the methyl group attached to it are disordered over two sets of sites in a 0.650 (3):0.350 (3) ratio. The cyclo-hexene ring in both the major and minor occupancy conformers adopts a half-chair conformation. The thio-phene ring is essentially planar (r.m.s. deviation = 0.05 Å). In the crystal, N-H⋯N hydrogen bonds involving the amino groups result in inversion dimers with R(2) (2)(12) graph-set motif. Further N-H⋯N hydrogen bonds involving the amino and carbonitrile groups generate zigzag chains along the a axis.

2-[(1,3-Benzodioxol-5-yl-methyl-idene)amino]-4,5,6,7-tetra-hydro-1-benzothio-phene-3-carbonitrile.

Project description:The title compound, C(17)H(14)N(2)O(2)S, crystallizes with two roughly planar mol-ecules in the asymmetric unit, in which the dihedral angles between the 1,3-benzodioxole-5-carbaldehyde moiety and the heterocyclic five-membered ring are 3.76?(5) and 5.33?(12)°. In each mol-ecule, a short C-H?S contact generates an S(5) ring. In the crystal, pairs of mol-ecules are linked by a weak C-H?N inter-action, forming dimers.

2-Amino-4,5,6,7-tetra-hydro-benzo[b]thio-phene-3-carbonitrile.

Project description:The title compound, C(9)H(10)N(2)S, was synthesized according to Gewald procedures by the reaction of cyclo-hexa-none with malonitrile and sulfur in the presence morpholine. The cyclo-hexane ring adopts a half-chair conformation and the thio-phene ring is essentially planar (r.m.s. deviation = 0.05 Å). The crystal packing is stabilized by two inter-molecular N-H⋯N hydrogen bonds, which link the mol-ecules into centrosymmetric rings with graph-set motif R(2) (2)(12).

2-Amino-7-oxo-4,5,6,7-tetra-hydro-1-benzothio-phene-3-carbonitrile.

Project description:In the title compound, C(9)H(8)N(2)OS, the benzothio-phene ring is substituted with amino, oxo and carbonitrile groups. The thio-phene ring is essentially planar (r.m.s. deviation = 0.0003 Å), while the cyclo-hexene ring is in a half-chair conformation. In the crystal, N-H⋯O hydrogen bonds generate chains of mol-ecules in a zigzag pattern along the b axis. Pairs of N-H⋯N hydrogen bonds form centrosymmetric head-to-head dimers about inversion centres, corresponding to an R(2) (2)(12) graph-set motif. In addition, rather weak N-H⋯S inter-actions are also present in the structure and the supra-molecular assembly is further consolidated by π-π stacking inter-actions between the benzothio-phene rings, disposed at a distance of 3.742 (3) Å.

Project description:In the title compound, C22H18N2O3S, disorder is found in the benzoyl group (A and B), as well as for four C atoms of the cyclo-hexene ring.

The dihedral angles between the mean plane of the thio-phene ring and the 4-nitro-benzene and phenyl rings are 30.9?(8) and 64.8?(3) (A) and 62.4?(7)° (B). The mean planes of the 4-nitro-benzene and the phenyl rings are almost perpendicular to each other, with dihedral angles of 85.4?(1) (A) and 83.9?(8)° (B). An extensive array of weak C-H?O inter-actions consolidate mol-ecules into a three-dimensional architecture, forming chains along [001] and [010] and layers parallel to (011).

2-[(1Z)-(9-Ethyl-9H-carbazol-3-yl)methyl-eneamino]-4,5,6,7-tetra-hydro-1-benzothio-phene-3-carbonitrile-benzene (2/1).

Project description:In the title compound, 2C(24)H(21)N(3)S·C(6)H(6), the two independent Schiff base mol-ecules (A and B) in the asymmetric unit differ in the orientation of the tetra-hydro-benzothio-phene ring system with respect to the carbazole ring system by 180° rotation about the C-C bond in the C-C=N-C linkage. The two mol-ecules also differ in the orientation of the ethyl groups [C-N-C-C torsion angle of 90.7?(3)° in mol-ecule A, and -79.4?(3)° in mol-ecule B]. In mol-ecule B, two methyl-ene C atoms of the cyclo-hexene ring are disordered over two sites with occupancies of 0.58?(1) and 0.42?(1). The cyclo-hexene rings in both mol-ecules adopt half-chair conformations. The dihedral angle between the thio-phene ring and the carbazole ring system is 8.07?(9)° in mol-ecule A [3.10?(9)° in mol-ecule B]. In the crystal structure, the independent mol-ecules are linked into dimers by inter-molecular C-H?N hydrogen bonds. In addition, C-H?? inter-actions are observed.
