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

ABSTRACT: 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).

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 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].

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.

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).

Ethyl 5-hy-droxy-6-oxo-4-phenyl-5,6-dihydro-4H-cyclo-penta-[b]thio-phene-5-carboxyl-ate.

Project description:In the title mol-ecule, C(16)H(14)O(4)S, the dihydro-cyclo-penta-thio-phenone ring system is almost planar, with an r.m.s. deviation of 0.060?Å from the best fit plane through all nine non-H atoms. The cyclo-penta-none ring adopts a severely flattened envelope conformation with the C atom carrying the OH and ethylcarboxylate substituents at the flap. This atom lies only 0.185?(3)?Å from the plane through the other four C atoms. The phenyl substituent is inclined at 43.37?(5)° to the dihydro-cyclo-penta-thio-phenone mean plane. In the crystal, mol-ecules are linked by pairs of O-H?O hydrogen bonds, forming inversion dimers with R(2) (2)(10) ring motifs. Weak C-H?O hydrogen bonds also link mol-ecules into chains along c, while an approximately orthogonal set of C-H?O contacts form chains along b, resulting in layers lying parallel to (100). Inversion dimers also form through weaker R(2) (2)(12) C-H?S contacts, which combine with C-H?O contacts to form stacks along b.
