In the title compound, C17H16N4OS2, the triazole and methylthiobenzylidene rings are nearly coplanar, making a dihedral angle of 6.52 (12)°. An intramolecular C—H⋯S hydrogen bond forms an S(6) ring motif. The hydroxybenzyl ring is almost normal to the triazole and methylthiobenzylidene rings, making dihedral angles of 78.56 (12) and 84.79 (11)°, respectively. In the crystal, molecules 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 interaction is observed [inter-centroid distance = 3.764 (3) Å], involving inversion-related methylthiobenzylidene rings.

The synthesis of title compound, (3), is illustrated in Fig. 3. A suspension of 4-(methylthio)benzaldehyde (2) (0.01 mol) in ethanol (15 ml) was added to 4-amino-3-(4-hydroxybenzyl)-1H-1,2,4-triazole-5(4H)-thione (1) (0.01 mol) and heated until a clear solution was obtained. To this a few drops of conc. H2SO4 were added as a catalyst and the mixture was refluxed for 36 h on a water bath. The precipitate formed was filtered and recrystallized from methanol to give the titled compound. Single crystals were obtained by recrystallization from acetic acid (m.p. 469—471 K).
Crystal data, data collection and structure
details are summarized in Table 2. The H atoms were fixed geometrically (O-H = 0.82 Å, N-H = 0.86 Å, and C—H = 0.93–0.97 Å) and allowed to ride on their parent atoms with Uiso(H) = 1.2Ueq(O,N,C).The title compound was synthesized, crystallized and its
is presented as part of our work on 3-methyl-1H-1,2,4-triazole-5(4H)-thione derivatives (Manjula et al., 2015).The molecular structure of the title compound is as shown in Fig 1. The methylsulfanylbenzylidene and triazole rings are almost coplanar with a dihedral angle of 6.52 (12) °. The hydroxybenzyl ring makes dihedral angles of 78.56 (12) ° and 84.79 (11) ° with the triazole and methylthiobenzylidene rings, respectively. An intramolecular interaction of the type C10—H10···S1 is observed (Fig. 1 and Table 1).
In the crystal, the molecules are connected through O1—H1···N2 and N1—H1A···O1 hydrogen bonds (Table 1) forming layers parallel to (010). The layers are linked by C17—H17C···N4 hydrogen bonds forming a three-dimensional structure (Fig. 2 and Table 1) . In addition, a parallel slipped π–π (Cg···Cgi) interaction is observed with an inter-centroid distance of 3.764 (3) Å [Cg is the centroid of ring C11—C16; inter-planar distance = 3.500 (1) Å; slippage 1.384 Å; symmetry code: (i) -x, -y+1, -z+1].

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |

The title compound was synthesized, crystallized and its crystal structure is presented as part of our work on 3-methyl-1H-1,2,4-triazole-5(4H)-thione derivatives (Manjula et al., 2015).
The molecular structure of the title compound is as shown in Fig 1. The methylsulfanylbenzylidene and triazole rings are almost coplanar with a dihedral angle of 6.52 (12) °. The hydroxybenzyl ring makes dihedral angles of 78.56 (12) ° and 84.79 (11) ° with the triazole and methylthiobenzylidene rings, respectively. An intramolecular interaction of the type C10—H10···S1 is observed (Fig. 1 and Table 1).
In the crystal, the molecules are connected through O1—H1···N2 and N1—H1A···O1 hydrogen bonds (Table 1) forming layers parallel to (010). The layers are linked by C17—H17C···N4 hydrogen bonds forming a three-dimensional structure (Fig. 2 and Table 1) . In addition, a parallel slipped π–π (Cg···Cgi) interaction is observed with an inter-centroid distance of 3.764 (3) Å [Cg is the centroid of ring C11—C16; inter-planar distance = 3.500 (1) Å; slippage 1.384 Å; symmetry code: (i) -x, -y+1, -z+1].
