Abstract
The title compound, C14H8Cl4N2O, is an unexpected side product of a re action to convert an acid chloride into a nitrile, the nature of which indicates the probable mechanism of the major reaction. In the crysta l structure, a conjugated and approximately planar cinnamide framework is attached to an almost perpendicular tetrachloro-substituted pyridy l ring, severe steric interactions overcoming the enhanced delocalizat ion which would occur with coplanarity.
