1,2-Diaryl(3-pyridyl)ethanone oximes. Intermolecular hydrogen bonding networks revealed by X-ray diffraction

Abstract

The synthesis of a set of 1-aryl-2-aryl(3-pyridyl)ethanones 1-5 and the corresponding ketoximes 6-9 is reported. Structural studies of oximes 6, 7 and 9 were performed in solution using 1H-NMR and in the solid state by X-ray crystallography, providing evidence of H-bonding networks. The crystal packing was controlled by homomeric intermolecular oxime⋯oxime H-bond interactions for 6 and cooperative oxime⋯N(pyridyl) and CH/π interactions for 7 and 9. © 2008 by MDPI.
