In the title thione, C26H36N6OS, the 1,2,4-triazole ring is planar (r.m.s. deviation = 0.020 Å) and the benzene ring is twisted out of this plane [dihedral angle = 62.35 (12)°]. Supramolecular zigzag chains feature in the crystal packing. These are sustained by O—HN(piperazine) hydrogen bonds, and are connected into the three-dimensional crystal structure by C—HS and C—HO interactions. The crystal studied was a racemic twin.

In the title compound, C31H38N6OS, the conformation about the N=C [1.285 (2) Å] imine bond is E. The piperazine ring has a chair conformation and occupies a position almost perpendicular to the plane through the triazole ring; the benzene ring forms a dihedral angle of 31.95 (10)° with the triazole ring. Overall, the molecule has the shape of a flattened bowl. The hydroxy group is disordered over two positions. The major component has a site-occupancy factor of 0.762 (3) and forms an intramolecular O—HN(imine) bond to close an S(6) loop. The minor component of the disordered hydroxy group forms an O—HN(piperazine) hydrogen bond. These, along with C—HS and C—HN interactions, link molecules into a three-dimensional architecture.

The asymmetric unit of the title dichloromethane hemisolvate, C24H33N5S·0.5CH2Cl2, comprises an adamantanyl/triazole derivative and half a CH2Cl2 molecule of crystallization; the latter is disordered about a twofold axis of symmetry. The piperazine ring has a chair conformation and the two N-bound substituents occupy equatorial positions. The piperazine residue is almost normal to the triazole ring [N—N—C—N torsion angle = −79.9 (3)°] so that to a first approximation, the molecule has an L-shape. Linear supramolecular chains parallel to [001] are formed via C—HS interactions. Two such chains are linked into a double chain via C—HCl interactions involving the disordered CH2Cl2 molecules of solvation.
