In the title compound, C11H9Cl2N3O3, the triazole and benzene rings are roughly parallel to one another [dihedral angle = 4.99 (2)°] because the C—O—C—C—O chain that links the two rings is folded [O—C—C—O = 8.60 (2)°] rather than fully extended. In the crystal, weak intermolecular C—H⋯N and C—H⋯O interactions are present, and π–π interactions are indicated by the short distances [3.749 (3) Å] between the centroids of the triazole and benzene rings.

To a 100 ml flask were added 10 mmol of (1H-1,2,4-triazol-1-yl)methanol and 11 mmol of triethylamine in 20 ml of dryed acetone, to which 10 mmol of 2-(2,4-dichlorophenoxy)acetyl chloride in 10 ml of acetone was then dropwise added with stirring on ice-cold water bath within 0.5 h. The reaction took place immediately, and a lot of white solid appeared. The mixture was heated and refluxed for 2 h, and then cooled to room temperature. After filtering and distilling in reduced pressure, a crude product was obtained and purified by flash
(silicagel, using ethyl ethanoate: cyclohexane = 1:3 as eluent) to afford the title compound. Single crystals suitable for X-ray measurements were obtained by recrystallization from ethyl acetate at room temperature.H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93 or 0.97 Å and with Uiso(H) = 1.2 times Ueq(C).
Compounds containing the triazole ring system are well known as efficient fungicides in agriculture, where they act by inhibiting the biosynthesis of ergosterol (Xu et al., 2002). In order to search for new triazole compounds with higher bioactivity, the title compound was synthesized and its structure is reported here.
In title compound, all bond lengths in the molecular are normal (Allen et al., 1987). Triazole ring (C10/C11/N1—N3) and benzene ring (C1—C6) are essentially parallel to one another (dihedral angle of 4.99 (2)°) because the C—O—C—C—O chain that links the two rings is folded [O—C—C—O torsion angle = 8.60 (2)°] rather than fully extended. π—π interactions are indicated by the short distance (Cg1···Cg1 distance of 3.749 (3) Å, symmetry code: 1-x,-y,-z) between the centroids of the triazole rings (C10/C11/N1—N3) (Cg1) and benzene rings C1—C6 (Cg2) (Table 1). There are weaker C—H···N, C—H···O intermolecular interactions, which stabilized the structure (Table 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 > 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. |

Compounds containing the triazole ring system are well known as efficient fungicides in agriculture, where they act by inhibiting the biosynthesis of ergosterol (Xu et al., 2002). In order to search for new triazole compounds with higher bioactivity, the title compound was synthesized and its structure is reported here.
In title compound, all bond lengths in the molecular are normal (Allen et al., 1987). Triazole ring (C10/C11/N1—N3) and benzene ring (C1—C6) are essentially parallel to one another (dihedral angle of 4.99 (2)°) because the C—O—C—C—O chain that links the two rings is folded [O—C—C—O torsion angle = 8.60 (2)°] rather than fully extended. π—π interactions are indicated by the short distance (Cg1···Cg1 distance of 3.749 (3) Å, symmetry code: 1-x,-y,-z) between the centroids of the triazole rings (C10/C11/N1—N3) (Cg1) and benzene rings C1—C6 (Cg2) (Table 1). There are weaker C—H···N, C—H···O intermolecular interactions, which stabilized the structure (Table 1).
