Comment top

Triazole derivatives exhibit growth-inhibiting activites against some microorganisms (Xu et al., 2002). In order to search for new triazole compounds with higher bioactivity, the title compound, (I), including triazole and benzotriazole, was synthesized.

The bond lengths and angles in (I) are within normal ranges (Allen et al., 1987) and comparable to those reported in the related compound 2-(1H-1,2,3-benzotriazol-1-yl)-1-(4-methylphenyl)-2- (1H-1,2,4-triazol-1-yl)ethanone (Wan et al., 2005). The benzotriazole group is essentially planar, with a dihedral angle of 1.9 (1)° between the benzene and triazole rings. The mean plane of the benzotriazole group makes dihedral angles of 74.3 (1) and 33.9 (1)° with the other triazole (N4/N5/C16/N6/C15) ring and the benzene (C1–C6) ring, respectively. The dihedral angle between the planes of the latter two aromatic rings is 69.9 (1)°. In the crystal structure, molecules are linked into ribbons by intermolecular C—H···N hydrogen bonds (Fig. 2 and Table 2). The packing is further stabilized by a π–π interaction between the benzene (C1–C6) rings, the distance between the centroids [Cg···Cg(1/2 − x, 3/2 − y, −z)] being 3.883 (2) Å.

Experimental top

The title compound was prepared according to the method of Wan et al. (2005).

Special details top

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.
