4-(2,4,6-Trinitroanilino)benzoic acid (p-picraminobenzoic acid), C13H8N4O8, obtained by the reaction of 2,4,6-trinitrobenzenesulfonic acid (picrylsulfonic acid) with 4-aminobenzoic acid in 2-propanol-water, forms a two-dimensional hydrogen-bonded network based on centrosymmetric cyclic R22(8) carboxylic acid dimers which are extended through lateral N-H...Ocarboxyl interactions. The amino group also makes an intramolecular N-H...Onitro hydrogen bond, while the two aromatic ring systems, are, as expected, non-coplanar, the C-C-N-C torsion angles being 152.0 (2) (picryl) and 136.1 (2)ࠨbenzoic acid).4-(2,4,6-Trinitroanilino)benzoic acid (p-picraminobenzoic acid), C13H8N4O8, obtained by the reaction of 2,4,6-trinitrobenzenesulfonic acid (picrylsulfonic acid) with 4-aminobenzoic acid in 2-propanol-water, forms a two-dimensional hydrogen-bonded network based on centrosymmetric cyclic R22(8) carboxylic acid dimers which are extended through lateral N-H...Ocarboxyl interactions.
