Abstract
In the title compound, C5H8N3 +·C24H20B−·C20H18N6, the 1,2-bis(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene molecule is essentially planar (r.m.s. deviation = 0.0045 Å) and aligned in nearly coplanar manner with the 2,6-diaminopyridinium ion, making a dihedral angle of 5.19 (5)°. The diaminopyridine molecule is protonated on the central pyridine N atom and the B atom bears the counter-charge. The amine groups of the diamino pyridinium cation form intramolecular N—H⋯N hydrogen bonds, resulting in linear and bent interactions with the naphthyridine ring system.
