Crystal structure of the pharmaceutical impurity 2-(4-chlorobenzoyl)pyridine

Source abstract

The title compound, C 12 H 8 ClNO, is a pharmaceutical impurity and possible intermediate in the synthesis of carbinoxamine. The aromatic rings of the molecule twist relative to one another resulting in an interplanar angle of 38.1 (1)°. In the extended structure, the molecules are packed into rippled sheets with offset face-to-face stacking of each aromatic ring with the equivalent ring in the neighboring molecule.
