1-[(Z)-2-Butyl­tellan­yl-1-chloro­ethen­yl]­cyclo­hex-1-ene

The Te^II atom in the title mol­ecule, C₁₂H₁₉ClTe, is coordinated in a V-shaped geometry by C atoms derived from the disparate organic substituents. A short intramolecular C—H...Cl contact occurs owing to the proximity of the ethene bond in the six-membered ring to the Cl atom. In the crystal, mol­ecules assemble into layers parallel to the ac plane, with the closest inter­actions between them being of the Te...Te type [3.9993 (16) Å].

4,4-Dimethyl-2-[3-nitro-2-phenyl-1-(phenyl­sulfan­yl)prop­yl]-4,5-dihydro-1,3-oxazole

In the title compound, C₂₀H₂₂N₂O₃S, the oxazoline ring is planar (r.m.s. deviation = 0.045 Å) and forms dihedral angles of 47.24 (8) and 10.11 (8)° with the S- and C-bound phenyl rings, respectively. The nitro group lies to the same side of the mol­ecule as the oxazoline ring but is orientated so as not to inter­act with the ring. Linear supra­molecular chains along [010] are formed via C—H...O and C—H...S contacts. Chains are consolidated into a three-dimensional architecture by C—H...π and van der Waals inter­actions.

1-Methyl-3,3-bis­(phenyl­sulfan­yl)piperidin-2-one

The piperidone ring in the title compound, C₁₈H₁₉NOS₂, is in a distorted half-chair conformation, distorted towards a twisted boat, with the central methyl­ene C atom of the propyl backbone lying 0.606 (2) Å out of the plane defined by the other five atoms (r.m.s. deviation = 0.1197 Å). One of the S-bound phenyl rings is almost perpendicular to the least-squares plane through the piperidone ring, whereas the other is splayed [dihedral angles = 75.97 (6) and 44.21 (7)°, respectively]. The most prominent feature of the crystal packing is the formation of helical supra­molecular chains along the b axis sustained by C—H...O inter­actions. The chains are consolidated into a three-dimensional architecture via C—H...π inter­actions whereby one S-bound phenyl ring accepts two C—H...π contacts.

3,3-Bis[(4-meth­oxy­phen­yl)sulfan­yl]-1-methyl­piperidin-2-one

The piperidone ring in the title compound, C₂₀H₂₃NO₃S₂, has a distorted half-chair conformation with the central methyl­ene atom of the propyl fragment lying 0.696 (1) Å out of the plane defined by the other five atoms (r.m.s. deviation = 0.071 Å). One of the S-bound phenyl rings is almost perpendicular to the mean plane through the piperidone ring, whereas the other is splayed [dihedral angles = 71.95 (6) and 38.42 (6)°]. In the crystal, C—H...O and C—H...π inter­actions lead to the formation of supra­molecular layers in the ab plane.
