(Z)-3-Meth­oxy-N-[(5-nitro­thio­phen-2-yl)methyl­idene]aniline

In the title compound, C₁₂H₁₀N₂O₃S, the dihedral angle between the benzene and thio­phene rings is 43.17 (4)°. The crystal structure is devoid of any hydrogen-bonding inter­actions. However, π–π inter­actions between the benzene and thio­phene rings [distance between ring centroids = 3.6850 (11) Å] stack the mol­ecules along the a axis. The absolute structure could not be determined as the crystal studied was a racemic twin with a BASF parameter of 0.31 (6).

(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)°.
