Study of the structure of 2-(hydroxyimino)-1-(1-naphthyl)ethanone by X-ray diffraction analysis

Abstract

In the present study the structure of 2-(hydroxyimino)-1-(1-naphthyl)ethanone has been investigated by X-ray diffraction. The aromatic system of 2-(hydroxyimino)-1-(1-naphthyl)ethanone is planar; it is characterized by rotation of the hydroxyiminoacetyl fragment atoms in relation to the plane of the ring by 31°. The deviation of the carbonyl oxygen atom from this plane is 0.714 Å, while the deviation of the hydroxyl oxygen atom is 1.237 Å. The parquet-stack packing of molecules in the crystal is due to the system of intermolecular hydrogen bonds of the C-H…O type with participation of the oxygen atom of the hydroxyl or carbonyl groups, as well as the O(2) H…O(1) and O(2) H…N(1) hydrogen bonds. The results of X-ray diffraction analysis have been registered in the Cambridge Crystallographic Data Center under the number CCDC 2445219.
