In the title compound, C24H24ClNO4, the dihydropyridine ring adopts a flattened boat conformation. The plane of the pyridine ring subtends dihedral angles of 74.54 (6) and 85.69 (5)° with those of the phenyl and chlorophenyl rings, respectively. The dihedral angle between the planes of the chlorophenyl and phenyl rings is 72.20 (7)°. In the crystal, molecules are linked into [100]C(6) chains by N—H...O hydrogen bonds. The chains are cross-linked by weak C—H...O interactions to generate a three-dimensional network.

In the racemic title compound, C26H24N2O2S2, one of the thiazine rings shows a twisted boat conformation (Q = 0.743 Å, θ = 92.1°) and the other a half-chair puckering (Q = 0.669 Å, θ = 54.3°). The terminal phenyl rings are almost parallel to each other [dihedral angle 21.71 (10)°]. Both of these rings are orthogonal to the central phenyl ring, subtending a dihedral angle of about 78° in each case. The extended structure is consolidated by C—H...O and C—H...S hydrogen bonds as well as aromatic ring interactions of parallel-displaced and T-type. The molecule has approximate C2 local symmetry but this is not carried over to its three-dimensional structure or the intermolecular interactions.

In the title compound, C24H27N5O2S·0.5H2O, the piperidine ring adopts a distorted boat conformation. The phenyl rings subtend dihedral angles of 69.7 (1) and 88.7 (1)° with the best plane through the piperidine moiety. In the crystal, symmetry-related molecules are linked through a network of C—H...O and C—H...N interactions, the former connecting them into zigzag chains along thec-axis direction and the latter forming anR22(4)motif. The dimer formation (C—H...N) and the repetition of symmetry-related molecules (C—H...O) along theb-axis direction stabilize the packing mode. The water molecule is located on a twofold rotation axis.
