N-(4-Acetyl­phen­yl)-4-meth­oxy­benzene­sulfonamide

The title compound, C₁₅H₁₅NO₄S, was obtained by the condensation of 4-amino­aceto­phenone and 4-meth­oxy­benzene­sulfonyl chloride. The dihedral angle between the benzene rings is 86.56 (9)° and the mol­ecule has an approximate V-shaped conformation. The C atom of the meth­oxy group is roughly coplanar with its attached ring [deviation = 0.177 (3) Å], as is the methyl C atom of the acetyl group with its ring [deviation = 0.065 (2) Å]. An intra­molecular C—H...O inter­action generates an S(6) ring. In the crystal, N—H...O and C—H...O hydrogen bonds link the mol­ecules into [010] chains. Weak C—H...π inter­actions are also observed.

3-(Adamantan-1-yl)-1-[(4-benzyl­piperazin-1-yl)meth­yl]-4-ethyl-1H-1,2,4-triazole-5(4H)-thione

In the title compound, C₂₆H₃₇N₅S, the piperazine ring adopts a chair conformation with the exocyclic N-C bonds in pseudo-equatorial orientations. The piperazine ring (all atoms) subtends dihedral angles of 79.47 (9) and 73.07 (9)° with the triazole and benzene rings, respectively, resulting in an approximate U-shape for the mol­ecule. No significant inter­molecular inter­actions are observed in the crystal.

N-(Adamantan-1-yl)-1,2,3,4-tetra­hydro­iso­quinoline-2-carbo­thio­amide

In the title compound, C₂₀H₂₆N₂S, the N-containing six-membered ring adopts a boat conformation and the dihedral angle between the thio­carbamide group and the benzene ring is 49.67 (9)°. An intra­molecular C—H...S hydrogen bond generates an S(6) ring motif. The N—H group is sterically hindered and there are no significant inter­molecular inter­actions beyond van der Waals contacts.
