Sodium 3,5-dinitrobenzoate, Na+·C7H3N2O6-, was obtained by evaporation at room temperature of an aqueous solution of ethylenediammonium 3,5-dinitrobenzoate in sodium hydroxide. The structure is trigonal and the benzoate ion has twofold crystallographic symmetry.

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.
