Abstract: In the title salt, C4H14N22+·2C6H3N2O5-, the dication acts as a hydrogen donor with all its N-H bonds involved in hydrogen bonds to the O atoms of the phenolate and nitro groups, and with six of its eight C-H bonds involved in interactions with the O atoms of the nitro groups of the surrounding 2,4-dinitrophenolates. The packing structure is stabilized by these hydrogen-bonding interactions.
