3-(Adamantan-1-yl)-1-[(4-benzyl­piperazin-1-yl)meth­yl]-4-[(E)-(2-hy­droxy­benzyl­idene)amino]-1H-1,2,4-triazole-5(4H)-thione

In the title compound, C(31)H(38)N(6)OS, 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—H⋯N(imine) bond to close an S(6) loop. The minor component of the disordered hy­droxy group forms an O—H⋯N(piperazine) hydrogen bond. These, along with C—H⋯S and C—H⋯N inter­actions, link mol­ecules into a three-dimensional architecture.
