Phenyl 2-Pyridyl Ketone at 150K

Abstract

Crystals of phenyl 2-pyridyl ketone, C12H9NO, suitable for X-ray diffraction were obtained by sublimation. Their structure, which was determined at 150 K, yields geometric parameters comparable with those found for the iso(valence)electronic analogues of benzophenone and 2,2′-dipyridyl ketone [Bock, Dienelt, Schoedel & Van (1997). Struct. Chem. In the press]. Both the phenyl and the pyridine rings are twisted considerably out of the central C—C(O)—C plane.
