Abstract
- In the title compound, 4C5H8N3+·2C8H4O42−·C5H7N3, the asymmetric unit consists of two protonated diaminopyridine cations, one phthalate anion and one half of a diaminopyridine molecule, which has twofold rotation symmetry and is disordered over two positions with a site-occupancy ratio of 0.534 (3):0.466 (3). In the disordered structure, both pyridine rings are essentially planar, with maximum deviations of 0.011 (2) and 0.006 (2) Å, and these two rings are inclined to one another at a dihedral angle of 79.86 (10)°. In the crystal structure, intermolecular N—H...O and C—H...O hydrogen bonds link the ions and molecules into a three-dimensional network. The structure is further stabilized by C—H...π interactions.
