Abstract:
The title Schiff base compound, C(11)H(9)N(3)O(3), was obtained from a condensation reaction of furan-2-carbaldehyde and 2-nitro-phenyl-hydrazine. The mol-ecule is roughly planar, the largest deviation from the mean plane defined by all non-H atoms being 0.097 (4). An in ntra-molecular N-H⋯O hydrogen bond might influence the planar conformation of the mol-ecule. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules, forming a chain.

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
