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

By Graham Smith, Urs D. Wermuth and Jonathon M. White


In the structure of 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 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 R2/1(4)] giving a convoluted two-dimensional network structure

Topics: crystal structure, hydrogen bonding, proton transfer, picrates, aniline yellow
