N-Cyclohexyl-2-[5-(4-pyridyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-ylsulfanyl]acetamide dihydrate.

In the title compound, C22H25N5OS.2H2O, the molecules are stacked in columns running along the b axis. In this arrangemant, the molecules are linked to each other by a combination of one two-centre N-H...O hydrogen bond and four two-centre O-H...O hydrogen bonds containing two types of ring motif, viz. R(4)4(10) and R(3)3(11). In the crystal structure, centrosymmetric pi-pi interactions between the triazole rings, with a distance of 3.691 (2) A between the ring centroids, also affect the packing of the molecules.
