چکیده
The title compound, C(17)H(12)S, which crystallises with two molecules in the asymmetric unit, features four fused rings forming an essentially planar mol-ecule, with maximum deviations from the mean plane of 0.078 (2) and 0.080 (2) Å for C atoms of the thio-phene and phenanthrene groups in both the mol-ecules. The crystal packing features weak C-H⋯π inter-actions.

The asymmetric unit of the title compound, C(30)H(27)N(2)O(4)PS(2), consists of two crystallographically independent mol-ecules. The thieno[2,3-b]thio-phene ring systems are planar. One of the terminal ethyl groups is disordered over two positions; the site occupancy factors are ca 0.7 and 0.3. The crystal structure is stabilized by N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds.

In the title compound, C14H16O4S2, the thieno[2,3-b]thio-phene ring systems are planar [maximum deviation = 0.008 (2) Å]. The mol-ecular conformation is stabilized by intra-molecular C-H⋯O hydrogen bonds, while the crystal packing is stabilized by C-H⋯O, C-H⋯π and π-π stacking [centroid-centroid distance = 3.6605 (14) Å] inter-actions, which lead to supra-molecular layers in the ab plane.

In the title compound, C23H22N2O4S, the pyrrolidine ring has an envelope conformation with the spiro C atom, shared with the indoline ring system, as the flap. The mean planes of the benzo-thio-phene and indoline ring systems are inclined to the mean plane of the pyrrolidine ring by 88.81 (8) and 79.48 (8)°, respectively, and to each other by 68.12 (5)°. In the crystal, mol-ecules are linked vi...

In the title compound, C22H14S, the r.m.s. deviation from the mean plane of the four-fused-ring naphtho-thio-phene unit is 0.056 Å. The dihedral angle between the naphtho-thio-phene plane and the pendant phenyl ring is 67.24 (6)°. In the crystal, weak C-H⋯π and π-π stacking [minimum centroid-centroid separation = 3.7466 (10) Å] inter-actions are observed, which together lead to (010) sheets.
