In the title compound, C14H18N2O2S, the piperidine ring has a chair conformation. Its mean plane is twisted with respect to the 4-methoxybenzoyl ring, with a dihedral angle of 63.0 (3)°. The central N—C(=S)—N(H)—C(=O) bridge is twisted with an N—C—N—C torsion angle of 74.8 (6)°. In the crystal, molecules are linked by N—H...O and C—H...O hydrogen bonds, forming chains along the c-axis direction. Adjacent chains are linked by C—H...π interactions, forming layers parallel to the ac plane. The layers are linked by offset π–π interactions [intercentroid distance = 3.927 (3) Å], forming a supramolecular three-dimensional structure.

In the title compound, C13H16N2O2S, the pyrrolidine ring has a twisted conformation on the central –CH2–CH2– bond. Its mean plane is inclined to the 4-methoxybenzoyl ring by 72.79 (15)°. In the crystal, molecules are linked by N—H...O and C—H...O hydrogen bonds to the same O-atom acceptor, forming chains along [001]. The chains are linked via slipped parallel π–π interactions [inter-centroid distance = 3.7578 (13) Å], forming undulating slabs parallel to (100).

In the title compound, C14H18N2O2S, the piperidine ring has a chair conformation. Its mean plane is twisted with respect to the 4-methoxybenzoyl ring, with a dihedral angle of 63.0 (3)°. The central N--C(=S)--N(H)--C(=O) bridge is twisted with an N--C--N--C torsion angle of 74.8 (6)°. In the crystal, molecules are linked by N--H⋯O and C--H⋯O hydrogen bonds, forming chains along the c-axis direction. Adjacent chains are linked by C--H⋯π interactions, forming layers parallel to the ac plane. The layers are linked by offset π--π interactions [intercentroid distance = 3.927 (3) Å], forming a supramolecular three-dimensional structure. [ABSTRACT FROM AUTHOR]
