In the title compound, C19H20N4OS, the 1,2,4-triazole ring forms dihedral angles of 58.64 (9) and 87.68 (9)° with the phenyl rings, which are inclined to one another by 43.30 (6)°. In the crystal, molecules are linked by N—H⋯O, N—H⋯S and C—H⋯S hydrogen bonds, forming chains propagating along the c-axis direction. Neighbouring chains are linked by three C—H⋯π interactions, forming layers parallel to the bc plane. Finally, the layers are linked by a fourth C—H⋯π interaction, forming a three-dimensional network.
Keywords: crystal structure; 4-amino-triazole; hydrogen bonding; C—H⋯π interactions.

Structure description
The synthesis and crystal structures of some Mannich base derivatives have been reported (Wang, et al., 2011; Shams, et al., 2011). Now, we present here the of the title 1,2,4-triazole derivative.
In the title compound, Fig. 1, the 1,2,4-triazole ring is almost planar, with an r.m.s. deviation of 0.0055 Å and a maximum deviation of 0.0087 (2) Å for atom C17. Atom C16 of the 1,2,4-triazole ring shows a distorted Csp2 state with bond angles of 103.06 (13)° for N1—C16—N3, 129.69 (12)° for N1—C16—S1, and 127.19 (12)° for N3—C16—S1. These values are similar to those reported for other triazole derivatives (Zhao et al., 2010; Gao et al., 2011). The other bond lengths and angles are comparable with those reported for related 1,2,4-triazole-5(4H)-thione derivatives (Al-Tamimi et al., 2010; Fun et al., 2009; Tan et al., 2010). The C10–C15 phenyl ring is normal to the triazole ring, making a dihedral angle of 87.68 (9)°, while the second phenyl ring (C1–C6) is inclined to the triazole ring by 58.64 (9)°. The phenyl rings are inclined to one another by 43.30 (6)°.
In the crystal, molecules are linked by N—H⋯O, N—H⋯S and C—H⋯S hydrogen bonds, forming chains propagating along the c-axis direction (Table 1 and Fig. 2). Neighbouring chains are linked by three C—H⋯π interactions, forming layers parallel to the bc plane, which are in turn linked by a fourth C—H⋯π interaction (C2—H2⋯Cg1iv) forming a three-dimensional network (Table 1 and Fig. 3).
Synthesis and crystallization
Benzaldehyde (2.0 mmol) and 3-(4-amino-5-thioxo-3-ethyl-4,5-dihydro-1H-1,2,4-triazol-1-yl)-3-(4-methoxyphenyl)-1-phenylpropan-1-one (2.0 mmol) were refluxed in ethanol. The reaction progress was monitored by TLC. The resulting precipitate was filtered off, washed with cold ethanol, dried and purified to give the target product as a colourless solid in 85% yield. Crystals of the title compound suitable for single-crystal X-ray analysis were grown by slow evaporation of a solution in chloroform-ethanol (1:1).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |
