The title compound, C10H9FN4S, crystallizes with two molecules (A and B) in the The dihedral angle between the planes of the trizole and fluorobenzene rings is 7.3 (3)° in molecule A and 41.1 (3)° in molecule B. Molecule A features an intramolecular C—H⋯S hydrogen bond, which closes an S(6) ring. In the crystal, A+B dimers linked by pairs of N—H⋯S hydrogen bonds occur, generating R22(8) loops. Weak π–π stacking contacts [centroid–centroid separation = 3.739 (6) Å] are also observed.

For the synthesis of titled compound (3), a suspension of 4-fluoro benzaldehyde (2) (0.01 mol) in ethanol (15 ml) was added to 4-Amino-3-methyl-1H-1,2,4-triazole-5(4H)-thione (1) (0.01 mol) and heated to get a clear solution (scheme). To this few drops of conc·H2SO4 were added as a catalyst and refluxed for 36hrs on water bath. The precipitate formed was filtered and recrystallized from suitable reagent to get the titled compound. Single crystals were obtained from acetic acid. (mp. 431–433 K).
Crystal data, data collection and structure
details are summarized in Table 1. The hydrogen atoms were fixed geometrically (C—H = 0.93–0.96 Å, N—H = 0.98 Å) and allowed to ride on their parent atoms with Uiso(H) = 1.2Ueq(C/N).As part of our crystal structural studies of new Schiff base derivatives useful for the preparation of biologically active 5-membered heterocyclic rings such as 3-methyl-1H-1,2,4-triazole-5(4H)-thione (Manjula et al., 2015). We now elucidate the
of the title molecule.The
consists of two symmetry-independent molecules (A and B) of the title compound as shown in Fig. 1. The conformation of the molecules are different as evidenced by the dihedral angles [7.3 (3) ° and 41.1 (3) ° between triazole and flurobenzene moiety for molecules A and B, respectively]. An intramolecular interaction of the type C8A—H8A···S1A is observed in molecule A and is absent in molecule B (Fig. 1).The packing of the molecules is as shown in figure 2. The molecules are linked through the N—H···S hydrogen bonds (Fig. 2) forming R22(8) ring motifs. A π–π interaction exists between centroid s: Cg1 A···Cg2 A (distance = 3.739 (6) Å) and Cg2 A···Cg1 A (distance = 3.740 (6) Å). Where, Cg1 A is N10A/C11A/N12A/N13A/C14A.

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. |

As part of our crystal structural studies of new Schiff base derivatives useful for the preparation of biologically active 5-membered heterocyclic rings such as 3-methyl-1H-1,2,4-triazole-5(4H)-thione (Manjula et al., 2015). We now elucidate the crystal structure of the title molecule.
The asymmetric unit consists of two symmetry-independent molecules (A and B) of the title compound as shown in Fig. 1. The conformation of the molecules are different as evidenced by the dihedral angles [7.3 (3) ° and 41.1 (3) ° between triazole and flurobenzene moiety for molecules A and B, respectively]. An intramolecular interaction of the type C8A—H8A···S1A is observed in molecule A and is absent in molecule B (Fig. 1).
The packing of the molecules is as shown in figure 2. The molecules are linked through the N—H···S hydrogen bonds (Fig. 2) forming R22(8) ring motifs. A π–π interaction exists between centroid s: Cg1 A···Cg2 A (distance = 3.739 (6) Å) and Cg2 A···Cg1 A (distance = 3.740 (6) Å). Where, Cg1 A is N10A/C11A/N12A/N13A/C14A.
