Abstract:
In the title mol-ecule, C(27)H(19)N(3)O(3), the imidazole and benzene rings make dihedral angles of 64.72 (4) and 64.02 (4)°, respectively, with the anthracene ring system (r.m.s. deviation = 0.043 Å). The nitro group is coplanar with the imidazole ring [dihedral angle = 1.1 (1)°]. The crystal packing is stabilized by weak π-π inter-actions with centroid-centroid distances of 3.7342 (10) and 3.7627 (9) Å.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
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...
