The title adduct (C9H11N3O6, Mr = 257.21) was synthesized and it crystallizes in orthorhombic, space group P212121 with a = 5.8835(19), b = 9.517(3), c = 20.399(6) (A), V= 1142.2(6) (A)3, Z = 4, Dc= 1.496 g/cm3, F(000) = 536,μ(MoKα) = 0.128 mm-1, the final R = 0.0396 and wR =0.0800 for 1047 observed reflections with I＞2σ(I). The compound is a 1:1 adduct of dimethylamine and 3,5-dinitrobenzoic acid which are linked by hydrogen bonds to form a two-dimensional network.The dimethylamine is protonated at the nitrogen atom with the proton from the carboxyl of 3,5-dinitrobenzoic acid.
