In the title compound, C17H19NO3S 2, the maximum deviation of atoms in the 2H-chromene ring system is 0.0097(14)Å and the piperidine ring adopts a chair conformation. The dihedral angle between the 2H-chromene ring and the piperidine ring (all atoms) is 87.59(8)°. In the crystal, inversion dimers linked by pairs of C - H⋯O interactions generate R2 2(22) loops. Further C - H⋯O hydrogen bonds link the dimers into [110] chains and weak aromatic π-π stacking [shortest centroid-centroid distance = 3.824(8)Å] is also observed. Source

In the title compound, C13H12Cl N O2S2, the 2H-chromene ring system is almost planar, with a maximum deviation of 0.005 (2) Å. The packing features C - H⋯S hydrogen bonds and π-π interactions between fused benzene rings of chromene [shortest centroid-centroid distances = 3.6553 (13) and 3.5551 (13) Å]. Source

In the title compound, C 23H 19Cl 2N 5OS, the triazole ring makes dihedral angles of 24.81 (18), 69.94 (19) and 35.68 (18)° with the dichlorophenyl, benzene and methoxyphenyl rings, respectively. An intramolecular N - H⋯N hydrogen bond occurs. In the crystal, inversion dimers linked by pairs of N - H⋯S hydrogen bonds occur. In addition, there are weak C - H⋯π interactions involving the dichlorophenyl and triazole rings. Source
