Abstract
In the title compound, C15H12ClN3O2S, the central oxadiazole ring forms dihedral angles of 7.72 (14) and 69.86 (12)° with the benzene and pyridine rings, respectively. The crystal packing is governed only by van der Waals interactions.

Comment
Heterocyclic compounds have been of great interest since many years, in particular due to the important role these compouns play in the development of medicinal chemistry (Mamolo et al., 2001; Liu et al., 2001; Demirbas et al., 2004). As a contribution to the structural characterization of new heterocyclic compounds, we report here the structure of the title compound.
In the title compound (Fig. 1) all bond lengths are within normal ranges (Allen et al., 1987). The dihedral angle between the central oxadiazole ring (N1/N2/O2/C8/C9) and the benzene (C2–C7) and pyridine (N3/C11–C15) rings are of 7.72 (14) and 69.86 (12)°, respectively. In the crystal structure, no hydrogen bonds, π···π interactions or C—H···π short contacts are observed, the structure being stabilized only by van der Waals interactions.
Experimental
The title compound was synthesized according to the previously reported literature methods (Zareef et al., 2008; Wu et al., 2011). Single crystals suitable for X-ray diffraction analysis were obtained by evaporation of an ethanol solution.
Refinement
All H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H distances of 0.93–0.97 Å, and with with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C) for methyl H atoms.

Special details
| 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. |
