5-(5-Chloro-2-hydroxybenzoyl)-1-methyl-3-nitropyridin-2(1H)-one

Abstract

In the title compound, C 13 H 9 ClN 2 O 5 , the dihedral angle between the planes of the benzene and pyridine rings is 55.30 (13) . The nitro group is tilted by 38.21 (10) with respect to the mean plane of the pyridine ring. In the crystal, molecules are linked by O-HÁ Á ÁO and C-HÁ Á ÁO hydrogen bonds, forming a three-dimensional framework. The crystal packing is further stabilized bystacking interactions [intercentroid distance = 3.5877 (17) Å ].
