4,4'-Azinodimethyldipyridinium Diperchlorate, C₁₂H₁₂N₄²⁺.2ClO₄⁻

The centrosymmetric 4,4′-azinodimethyl­dipyridinium cations, C₁₂H₁₂N₄²⁺, are planar and lie in planes parallel to the c axis. There is a strong intermolecular hydrogen bond, N1—H...O4ⁱ [2.896 (3) Å; symmetry code: (i) −x, 1 − y, −z] and a number of weaker hydrogen bonds between the C atoms of the pyridine rings and the O atoms of the perchlorate anions [3.234–3.246 (4) Å].
