2-(2,6-Dichlorophenyl)-N-(1,3-thiazol-2-yl)acetamide

In the title compound, C11H8Cl2N2OS, the mean plane of the dichlorophenyl ring is twisted by 79.7 (7)° from that of the thiazole ring. In the crystal, molecules are linked via pairs of N—H⋯N hydrogen bonds, forming inversion dimers which stack along the a-axis direction.

Amides are also used as ligands due to their excellent coordination abilities (Wu et al., 2008(Wu et al., , 2010. Crystal structures of some acetamide derivatives viz., (Butcher et al., 2013a,b) have been reported. In view of the importance of amides, we report herein the crystal structure of the title compound, C 11 H 8 Cl 2 N 2 OS, (I).

Refinement
All of the H atoms were placed in their calculated positions and then refined using the riding model with Atom-H lengths of 0.95Å (CH) or 0.99Å (CH 2 ). Isotropic displacement parameters for these atoms were set to 1.18-1.23 (CH, CH 2 ) times U eq of the parent atom.

Computing details
Data collection: CrysAlis PRO (Agilent, 2012); cell refinement: CrysAlis PRO (Agilent, 2012); data reduction: CrysAlis PRO (Agilent, 2012); program(s) used to solve structure: SHELXS97 (Sheldrick, 2008); program(s) used to refine structure: SHELXL97 (Sheldrick, 2008); molecular graphics: SHELXTL (Sheldrick, 2008); software used to prepare material for publication: SHELXTL (Sheldrick, 2008).    Reaction scheme. Special details 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 F 2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F 2 , conventional R-factors R are based on F, with F set to zero for negative F 2 . The threshold expression of F 2 > σ(F 2 ) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
