1,3-Dimethyl-5,6,7,8-tetra-hydro-4H-cyclo-hepta-[c]thio-phene-4,8-dione.

ABSTRACT: In the title compound, C(11)H(12)O(2)S, the C and S atoms of the central thio-phene and the methyl groups, and the two carbonyl groups of the cyclo-hepta-nedione are almost coplanar [maximum deviation from the mean plane = 0.221?(2)?Å]. The packing is stabilized by ?-? inter-actions between the conjugated thio-phenes, the shortest centroid-centroid distance between thio-phene rings being 3.9759?(10)?Å.

Project description:The title compound, C(16)H(15)N(3)O(2)S, was synthesized by the reaction of 2-amino-5,6,7,8-tetra-hydro-4H-cyclo-hepta-[b]thio-phene-3-carbonitrile and o-fluoro-nitro-benzene. The thio-phene and nitro-phenyl rings and amino and carbonitrile groups are coplanar with a maximum deviation of 0.046?(2)?Å and a dihedral angle of 0.92?(6)° between the rings. The cyclo-hepta ring adopts a chair conformation. Intra-molecular N-H?O and C-H?S inter-actions occur. In the crystal, the mol-ecules form layers that are linked by ?-? stacking inter-actions between the thio-phene and benzene rings [centroid-centroid distances = 3.7089?(12) and 3.6170?(12)?Å].

2-[(2-Hy-droxy-naphthalen-1-yl)methyl-idene-amino]-5,6,7,8-tetra-hydro-4H-cyclo-hepta-[b]thio-phene-3-carbonitrile.

Project description:Two independent mol-ecules, A and B, comprise the asymmetric unit of the title compound, C(21)H(18)N(2)OS, with the difference in the angle of orientation between the naphthalene ring system and the mean plane of the cyclo-heptyl ring [16.13?(1) in A and 11.48?(5)° in B], being evident. The cyclo-heptyl ring adopts a distorted chair conformation in each mol-ecule with r.m.s. deviations of 0.2345?(4) (A) and 0.2302?(4)?Å (B). Intra-molecular O-H?N hydrogen bonding generates planar six-membered S(6) loops with r.m.s. deviations of 0.0099?(1) (A) and 0.0286?(1)?Å (B).

Ethyl 2-(3-phenyl-thio-ureido)-5,6-di-hydro-4H-cyclo-penta-[b]thio-phene-3-carboxyl-ate.

Project description:In the title compound, C(17)H(18)N(2)O(2)S(2), the angle between the mean plane defined by the atoms of the 5,6-dihydro-4H-cyclo-penta-[b]thio-phene moiety (r.m.s. deviation = 0.19 Å) and the phenyl ring is 72.8°(2). The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O inter-action, which generates an S(6) ring motif. In the crystal, pairs of N-H⋯S hydrogen bonds link the mol-ecules to form inversion dimers with an R(2) (2)(8) ring motif.

4-Imino-2,7-dimethyl-5,6,7,8-tetra-hydro-4H-1-benzothieno[2,3-d]pyrimidin-3-amine.

Project description:In the title compound, C(12)H(16)N(4)S, the fused benzothio-phene and the pyrimidine rings are coplanar [dihedral angle = 1.61 (6)°]. Three C atoms of the cyclohexene ring (at positions 3, 6 and 7) are disordered over two sites with an occupancy ratio of 0.702 (8):0.298 (8). The cyclo-hexene ring in both the major and minor components adopts a half-chair conformation. The crystal structure is stabilized by N-H⋯N and C-H⋯N inter-actions, resulting in the formation of inversion dimers with R(2) (2)(10) and R(2) (2)(12) graph-set motifs.

(4S)-3-Methyl-5,6,7,8-tetra-hydro-4H-spiro-[[1,2]oxazolo[5,4-b]quinoline-4,3'-indole]-2',5-dione.

Project description:In the title compound, C18H15N3O3, the dihedral angle between the mean planes of the quinoline and indole ring systems [r.m.s. deviations = 0.189 (2) and 0.027 (2) Å, respectively] is 88.65 (5)°. The cyclo-hexene ring of the quinoline ring system adopts an envelope conformation with the central -CH2- C atom as the flap. In the crystal, mol-ecules are linked by two pairs of N-H⋯O hydrogen bonds, forming inversion dimers, and enclosing R 2 (2)(14) ring motifs. This arrangement results in the formation of chains propagating along [100].
