In the title compound, C15H12ClN5O, the mean planes of the benzotriazole and chlorophenyl fragments form a dihedral angle of 70.8 (1)°. In the crystal, molecules are linked into infinite chains along the a axis by N—H⋯O hydrogen bonds. Weak intermolecular C—H⋯N hydrogen bonds further link these chains into layers parallel to the ab plane. The crystal studied was a racemic twin.

The title compound was synthesized by the reaction of 2-(1H-1,2,3-benzotriazol-1-yl)acetohydrazide (1 mmol, 191.2 mg) with 2-chlorobenzaldehyde(1 mmol, 140.6 mg) in ethanol(20 ml)under reflux conditions (348 K) for 5 h. The solvent was removed and the solid product recrystallized from tetrahydrofuran. After five days colourless crystals suitable for X-ray diffraction study were obtained.
All H atoms were placed in idealized positions (C—H = 0.93— 0.97 Å, N—H = 0.86 Å) and refined as riding atoms. For those bound to C, Uiso(H) = 1.2 or 1.5Ueq(C). while for those bound to N, Uiso(H) = 1.2 Ueq(N).
In continuation of our structural studies of benzotriazole derivatives (Shi et al., 2007a,b; Ji et al., 2008), herewith we present the
of the title compound, (I).In (I) (Fig. 1), the bond lengths and angles are normal and in a good agreement with those observed in the related compounds (Shi et al., 2007a,b; Ji et al., 2008). The mean planes of the benzotriazole and chlorophenyl fragments form a dihedral angle of 70.8 (1)°.
In the
the molecules are linked into infinite chains along the a axis by N—H···O hydrogen bonds (Table 1; Fig. 2). Weak intermolecular C—H···N hydrogen bonds (Table 1) link further these chains into layers parallel to ab plane.For related structures, see: Shi et al. (2007a,b); Ji et al. (2008).

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. |

In continuation of our structural studies of benzotriazole derivatives (Shi et al., 2007a,b; Ji et al., 2008), herewith we present the crystal structure of the title compound, (I).
In (I) (Fig. 1), the bond lengths and angles are normal and in a good agreement with those observed in the related compounds (Shi et al., 2007a,b; Ji et al., 2008). The mean planes of the benzotriazole and chlorophenyl fragments form a dihedral angle of 70.8 (1)°.
In the crystal structure, the molecules are linked into infinite chains along the a axis by N—H···O hydrogen bonds (Table 1; Fig. 2). Weak intermolecular C—H···N hydrogen bonds (Table 1) link further these chains into layers parallel to ab plane.
