2,6-Diaminopyridinium 2-carboxybenzoate

Abstract

In the crystal of the title molecular salt, C5H8N3+·C8H5O4−, the diaminopyridine cation and the phthalate anion are linked by a pair of N—H...O hydrogen bonds. Within the phthalate anion, an almost symmetrical O—H...O hydrogen bond is observed. The ion pairs are linked by further N—H...O hydrogen bonds, generating a two-dimensional network lying parallel to (10overline{1}).
