Molecular self-assembling of nitro derivatives of 2-oxo1-naphthaldimine via C-H'''O intermolecular hydrogen bonds

Schiff bases of type Ar-CH=N-Ar derivated from 2-hydroxy-1-naphthaldehyde and m-nitro (1) and p-nitro aniline (2) are prepare by template condensation. Compounds 1 and 2 exist in the solid state as the cis-quinoid (or ketoamino) tautomers characterized by strong, resonance assisted hydrogen bond of the N-H'''O type.
