biostudies-literatureUnknown66(Pt 2)Toumi Akriche SThe title compound, C(5)H(6)N(3)O(2) (+)·ClO(4) (-), is comprised of discrete perchlorate anions and 2-amino-3-nitro-pyridinium cations. The anion has a typical tetra-hedral geometry while the cation presents a nearly planar [maximum deviation = 0.007 (8) Å] pyridinium ring. Undulating [C(5)H(6)N(3)O(2) (+)](n) chains extending along the c-axis direction are linked via N-H⋯O hydrogen bonds. The cations are further connected to the anions by N-H⋯O hydrogen bonds and weak C-H⋯O inter-actions, leading to the formation of a three-dimensional network.Acta crystallographica.
