3-Isopropyl-1-{2-[(1-methyl-1H-tetra­zol-5-yl)sulfan­yl]acet­yl}-2,6-di­phenyl­piperidin-4-one hemihydrate

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 the c-axis direction and the latter forming an R²₂(4)motif. The dimer formation (C—H...N) and the repetition of symmetry-related molecules (C—H...O) along the b-axis direction stabilize the packing mode. The water mol­ecule is located on a twofold rotation axis.
