Networks of intermolecular interactions involving nitro groups in the crystals of three polymorphs of 9-aminoacridinium 2,4-dinitrobenzoate ⋠ 2,4-dinitrobenzoic acid

- Three polymorphs of 9-aminoacridinium 2,4-dinitrobenzoate ⋅ 2,4-dinitrobenzoic acid have been structurally characterized.
- The N-H⋯O and O-H⋯O hydrogen bonds between 9-aminoacridine and carboxylic acid have been analysed.
- The intermolecular interactions involving nitro groups have also been analysed.
