1-Cyclohexyl-5-(2-hydroxybenzoyl)-3-nitropyridin-2(1H)-one

In the title compound, C18H18N2O5, the cyclo­hexane ring adopts a chair conformation, and its mean plane is almost normal to the central pyridin-2-one ring with a dihedral angle of 87.94 (8)°. The latter ring is inclined to the 2-hy­droxy­benzoyl ring by 50.92 (8)°. There is an intra­molecular O—H⋯O hydrogen bond in this unit forming an S(6) ring motif. The NO2 group is disordered over two orientations of equal occupancy. In the crystal, mol­ecules are linked via C—H⋯O hydrogen bonds, forming chains propagating along [001]. Inversion-related chains are linked by C—H⋯π inter­actions, forming columns along the c-axis direction.
