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

In the title co-crystal, C(6)H(6)N(2)O(2.)C(10)H(12)O(4), the two components are held together by an N-H⋯O(aldehyde) hydrogen bond. Adjacent co-crystals are linked by weaker N-H⋯O(nitro) 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.
