2-Amino-3-nitropyridinium perchlorate

Abstract

The title compound, C5H6N3O2+·ClO4-, 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 [C5H 6N3O2+] 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 interactions, leading to the formation of a three-dimensional network.
