Abstract: The co-crystal of ethylenediammonium bis(3,5-dinitrobenzoate) and 3,5-dinitrobenzoic acid, namely ethylenediaminium-3,5-dinitrobenzoate-3,5-dinitrobenzoic acid (1/2/2), C₂H₁₀N₂²⁺·2C₇H₃N₂O₆^-·2C₇H₄N₂O₆, has as the asymmetric unit one 3,5-dinitrobenzoic acid molecule, one 3,5-dinitrobenzoate ion and one-half of the ethylenediammonium ion, as this cation lies on an inversion centre. Each ethylenediammonium ion is hydrogen bonded to four benzoate ions and two benzoic acid molecules.
