5-Phenyl-1,2,5-di­thia­zepane

In the title compound, C₁₀H₁₃NS₂, the seven-membered ring adopts a chair conformation. The S—S bond length is 2.0406 (5) Å and the C—S—S—C torsion angle is −83.89 (7)°. The amine group is sp²-hybridized. In the crystal, mol­ecules are linked into chains along [001] by weak inter­molecular S...S contacts of 3.5246 (5) Å.

6-Bromo-N-(6-bromo­pyridin-2-yl)-N-[4-(2,3-di­hydro­thieno[3,4-b][1,4]dioxin-5-yl)phen­yl]pyridin-2-amine

In the title mol­ecule, C₂₂H₁₅Br₂N₃O₂S, the central benzene ring forms dihedral angles of 12.39 (17), 56.66 (17) and 74.71 (19)°, respectively, with the mean planes of the thio­phene and two pyridine rings. The dioxane ring is in a half-chair conformation. An intra­molecular C—H...O hydrogen forms an S(6) ring. The amine N atom is sp²-hybridized.

4-(2,3-Di­hydro­thieno[3,4-b][1,4]dioxin-5-yl)aniline

In the title mol­ecule, C₁₂H₁₁NO₂S, the dioxane-type ring adopts a half-chair conformation. The thio­phene ring forms a dihedral angle of 12.53 (6)° with the benzene ring. In the crystal, N—H...O, hydrogen bonds link mol­ecules, forming chains along the c-axis direction. A weak intra­molecular C—H...O hydrogen bond is observed.

(E)-4-[7-(2,3-Di­hydro­thieno[3,4-b][1,4]dioxin-5-yl)-2,1,3-benzo­thia­diazol-4-yl]-2-[(neo­pentyl­imino)­meth­yl]phenol

In the title mol­ecule, C₂₄H₂₃N₃O₃S₂, the benzo­thia­diazole ring system is essentially planar, with an r.m.s. deviation of 0.020 (8) Å. The thio­phene and hy­droxy-substitiuted rings form dihedral angles of 23.43 (9) and 35.45 (9)°, respectively, with the benzo­thia­diazole ring system. An intra­molecular O—H...N hydrogen bond is observed. In the crystal, weak C—H...O hydrogen bonds and π–π stacking inter­actions [centroid–centroid distance = 3.880 (3) Å] link mol­ecules into chains along [100]. In addition, there are short S...S contacts [3.532 (3) Å] which link these chains, forming a two-dimensional network parallel to (010).
