✦ Synopsis
The molecules of the title compound, C 6 H 4 ClNO 2 , are almost completely planar. Hydrogen bonds of the form O-HÁ Á ÁN interconnect the molecules to form infinite chains, which are also planar and which are packed face-to-face to form well defined layers of molecules.

The title compound, C~7~H~5~ClF~3~NO, was synthesized by the reaction of 2-chloro-3-hydroxypyridine with 2-chloro-1,1,1-trifluoroethane. The pyridine ring and the O and Cl atoms are nearly coplanar, the largest deviation from the mean plane being 0.078 (6) Å. Bioassay indicates that the title compou
