5-Chloro-4′-ethyl-3H-spiro­[1,3-benzo­thia­zole-2,1′-cyclo­hexa­ne]

In the title compound, C₁₄H₁₈ClNS, the 2,3-dihydro-1,3-thia­zole ring adopts an envelope with the S,N-bound C atom at the flap and the cyclo­hexane ring adopts a chair conformation. In the crystal, N—H...S hydrogen bonds with C(5) motifs connect the mol­ecules into chains parallel to the c axis.

4′-tert-Butyl-5-chloro-3H-spiro­[1,3-benzothia­zole-2,1′-cyclo­hexa­ne]

In the title compound, C₁₆H₂₂ClNS, the nine-membered 2,3-dihydro-1,3-benzothia­zole ring system is essentially planar, with a maximum deviation of 0.025 (2) Å for the N atom. Its plane is almost perpendicular to the main plane of the substituted cyclo­hexane ring, which adopts a chair conformation. In the crystal, the molecules are linked by C—H...π inter­actions.
