Description
Summary:The asymmetric unit of the title compound, 3C5H6ClN2+·3C8H5O4−·C8H6O4, contains three independent 2-amino-5-chloropyridinium cations, three independent hydrogen phthalate anions and one phthalic acid molecule. In the crystal structure, there are two kinds of supramolecular tapes. One is formed by two independent cations with two anions through N—H...O and C—H...O hydrogen bonds. Another one is formed by the other cation and anion, and the phthalic acid molecule via N—H...O, O—H...O and C—H...O hydrogen bonds. These two tapes are connected by an O—H...O hydrogen bond, forming a double-tape structure.
