Abstract: The title compound, C₁₂H₁₂N₄O²⁺·2NO₃^-, crystallizes as 1-(4-pyridinio)-2'-[4-pyridinio-(E)-methylidene]hydrazide cations and nitrate anions. An extensive hydrogen-bonding network, primarily N-HO interactions, but with supporting C-HO contacts, leads to a three-dimensional matrix structure, which is best considered as a cationic framework with bridging nitrate anions. The basic feature of the cationic framework is a zigzag chain, which runs along the [101] direction. The chains pack to generate two-dimensional sheets which lie parallel to the (101) plane and stack in the [01] direction to give the three-dimensional matrix.
