In the title compound, C24H20BrF2N3O3S, the triazole ring (r.m.s. deviation = 0.0107 Å) makes dihedral angles of 28.18 (14), 63.76 (14) and 77.01 (18)°, respectively, with the trimethoxy-, bromo-, and difluoro-substituted benzene rings. The C atoms of the meta methoxy groups are roughly coplanar with their ring [displacements = −0.289 (4) and 0.083 (7) Å], whereas the C atom of the para group is displaced [1.117 (3) Å]. In the crystal, inversion dimers linked by two pairs of C—H⋯O hydrogen bonds occur. The ring motif of the two hydrogen bonds to their symmetry-generated O-atom acceptors is R22(8).

To a solution of 4-(4-bromophenyl)-5-(3,4,5-trimethoxyphenyl)-4H-1,2,4- triazole-3-thiol (1 g, 0.0023 mol) in dry acetonitrile (20 ml) was added potassium carbonate (0.65 g, 0.0047 mol) followed by 2,6-difluorobenzyl bromide (0.52 g, 0.0025 mol) at room temperature. After the addition, the reaction mixture was stirred at room temperature for 6 hr. Progress of reaction was monitored by TLC. After the completion of the reaction, the reaction mixture was concentrated and purified by
using pet ether, ethyl acetate as an to afford title compound as a colourless solid. Yield 1.1 g, 85%. M.p: 448–453 K.All the H atoms were positioned geometrically and refined using a riding model with Uiso(H) = 1.2 or 1.5Ueq(C) (C—H = 0.93, 0.96 or 0.97 Å). A rotating group model was applied to the methyl group. In the final
one outliner (-2 0 8) was omitted.Data collection: APEX2 (Bruker, 2009); cell

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. |
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 > σ(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. |

As part of our ongoing studies of 1,2,4-triazole derivatives (Fun et al., 2011), we now describe the structure of the title compound, (I).
In the title compound (Fig. 1), the triazole (N1–N3/C7/C8) ring is essentially planar with maximum deviation of 0.015 (3) Å at atom C8. The central triazole ring makes dihedral angles of 28.18 (14)°, 63.76 (14)° and 77.01 (18)° respectively with the methoxy (C1–C6), bromo (C9–C14), and difluoro (C16–C21) substituted phenyl rings. The bond lengths are comparable to a related structure (Fun et al., 2011).
In the crystal (Fig. 2), the intermolecular C13—H13A···O1 and C14—H14A···O2 hydrogen bonds (Table 1) link the molecules to form R22 (8) ring motifs (Bernstein et al., 1995), leading to the formation of dimers.
