【 摘 要 】

The title compound, C15H11NO4, crystallizes in two polymorphic forms, centrosymmetric monoclinic and chiral ortho­rhom­bic. The geometry of the mol­ecules in the two polymorphs is slightly different, possibly due to inter­molecular inter­actions. There are no classical hydrogen bonding in these two structures. However, a number of C—H⋯O inter­molecular inter­actions, involving both O atoms of the nitro as well the benzoyl groups, stabilize the crystal structures.
