2-(4-Aminophenyl)-1-phenyldiazenium 2,4,6-trinitrophenolate

In the title salt, C12H12N3+·C6H2N3O7 , the diazenyl group of the 4-(phenyldiazenyl)aniline molecule is protonated and forms a hydrogen bond with the phenolate O-atom acceptor of the picrate anion. Structure extension occurs through two symmetrical inter-ion three-centre amine N—H...O,O′nitro hydrogen-bonding associations [graph set R12(4)], giving a convoluted two-dimensional network structure.
