The crystal structure of 4-aminopyridinium 3,5-dinitrobenzoate, C 12 H 10 O 6 N 4 , has been determined by single-crystal X-ray diffraction technique. The title compound crystallizes in the monoclinic sp. gr. P21/n with the unit cell parameters: a = 7.4726(3) Å, b = 23.0898(9) Å, c = 8.0744(4) Å, V = 1338.64(10) Å 3 , Z = 4. The asymmetric unit of the compound consists of one 3,5-dinitrobenzoate anion and 4-aminopyridine cation. The adjacent anions and cations are linked through two N−H···O hydrogen bonds, N2−H2 A ···O5 and N 2 −H2 B ···O6, to form an infinite chain of anions and cations, extended along the [010] direction.
