2-Methyl-3-nitro-N-{(E)-[5-(4-nitro­phen­yl)furan-2-yl]methyl­idene}aniline

In the title Schiff-base type compound, C₁₈H₁₃N₃O₅, the central furan ring makes dihedral angles of 12.80 (7) and 51.43 (4)° with the terminal benzene rings. The dihedral angle between the benzene rings is 45.43 (3)°. In the crystal, C—H...O hydrogen bonds link the mol­ecules into layers parallel to (010). In addition, there are π–π stacking inter­actions within the layer [centroid–centroid distance = 3.584 (1) Å] and between the layers [centroid–centroid distance 3.751 (1) Å].

(E)-1-[(3-Bromo­phen­yl)imino­meth­yl]naphthalen-2-ol

The title compound, C₁₇H₁₂BrNO, exists in an enol–imine form and the mol­ecular structure features an intra­molecular O—H...N hydrogen bond. The dihedral angle between the benzene ring and the naphthalene ring system is 17.27 (15)°.
