title: Crystal structure of (E)-3-(4-hy-droxy-benz-yl)-4-{[4-(methyl-sulfan-yl)benzyl-idene]amino}-1H-1,2,4-triazole-5(4H)-thione.
abstract: In the title compound, C17H16N4OS2, the triazole and methyl-thio-benzyl-idene rings are nearly coplanar, making a dihedral angle of 6.52 (12)°. An intra-molecular C-H⋯S hydrogen bond forms an S(6) ring motif. The hy-droxy-benzyl ring is almost normal to the triazole and methyl-thio-benzyl-idene rings, making dihedral angles of 78.56 (12) and 84.79 (11)°, respectively. In the crystal, mol-ecules are linked through O-H⋯N and N-H⋯O hydrogen bonds, forming layers parallel to the ac plane. The layers are linked via C-H⋯N hydrogen bonds, forming a three-dimensional structure. In addition, a short π-π inter-action is observed [inter-centroid distance = 3.764 (3) Å], involving inversion-related methyl-thio-benzyl-idene rings.
