4-Nitroaniline–2,4,6-trimethoxybenzaldehyde (1/1)

In the title co-crystal, C6H6N2O2.C10H12O4, the two components are held together by an N—H⋯Oaldehyde hydrogen bond. Adjacent co-crystals are linked by weaker N—H⋯Onitro hydrogen bonds, forming a linear chain. The two aromatic rings of the components are aligned at 75.2 (1)°. The crystal studied was a non-merohedral twin with a 24% minor component.
