The X-ray crystal structure of the 2:1 anthranilic acid-picric acid complex, 2C7H7NO2.C6H3N3O7, shows extensive stacking interactions, where picric acid is sandwiched between two crystallographically independent anthranilic acid molecules, with spacings of 3.29 and 3.33 Å. The carboxyl and amino groups of anthranilic acid are neutral and the former group is hydrogen bonded to the polar nitro and phenol O atoms of neighboring picric acid molecules. The present results indicate the superior -donating ability of anthranilic acid, as well as a superior hydrogen-bonding ability, in its interaction with an acceptor molecule such as picric acid.
