摘要：

The crystal structure of the title compound, C5H8N3+ (.) C7H4NO4- or (pydaH)(+)(pydcH)(-) (pyda is 2,6-diaminopyridine and pydcH(2) is pyridine-2,6-dicarboxylic acid), shows both intra- and intermolecular proton transfers from carboxyl groups to the ring N atoms of (pydc)(2-) and pyda. This determination corrects a previous report which formulated this compound as (pydaH(2))(2+)(pydc)(2-) [Moghimi, Ranjbar, Aghabozorg, Jalali, Shamsipur, Yap & Rahbarnoohi ( 2002), J. Mol. Struct. 605, 133 - 149]. Ion-pairing, hydrogen-bonding and pi-pi stacking interactions link the fragments to form a self-associated system.
