Abstract

In the title compound, C12H11NO3, the mol­ecules have two intra­molecular C—H⋯O hydrogen bonds that define an S(6)S(5) pattern. The mol­ecules are linked by N—H⋯O hydrogen bonds into a centrosymmetric dimer. These dimers are linked by further C—H⋯O hydrogen bonds, so forming a [100] ribbon of R22(8)R44(18)[R44(20)] rings, a [1\overline{1}\overline{1}] chain of alternating R22(8) and R22(22) rings, and an [010] complex chain of R42(18) rings. The combination of the [100] ribbon, the [1\overline{1}\overline{1}] chain and the [010] chain results in the formation of a three-dimensional network structure.
