Bis(2-amino-6-methyl-pyridinium) 3-nitro-benzene-1,2-di-carboxyl-ate

摘要

In the title mol-ecular salt, 2C6H9N2+·C8H3NO62?, the cations are protonated at their pyridine N atoms. The cations and anion are linked by N—H?O and C—H?O hydrogen bonds and a?π–π?inter-action [centroid-to-centroid distance = 3.7299?(13)??]. In the crystal, N—H?O hydrogen bonds link the anions and cations into an infinite two-dimensional network parallel to (10-1). N—H?O hydrogen bonds generate?R12(4),?R21(6),?R24(18) and?R22(11) ring motifs. The structure also features weak C—H?O and C—H?π?inter-actions, which lead to the formation of a three-dimensional network.
