Abstract

The title hydrated salt, 2C5H8N3 +.C8H5O4-. NO3-.H2O, was obtained fortuitously from the reaction between 2,6-diaminopyridine, phthalic acid and Co(NO3)2.6H2O at 343 K. The asymmetric unit consists of two crystallographically independent 2,6-diaminopyridinium cations, a hydrogen phthalate anion, a nitrate ion and a water molecule of crystallization which in the crystal structure are linked by intermolecular O— H...O and N—H...O hydrogen bonds into a three-dimensional network. In the hydrogen phthalate anion, there is a very strong intramolecular O—H...O hydrogen bond.
