2-Amino-3-nitro pyridium perchlorate.

Abstract

The title compound, C5H6N3O2 +_ClO4_, is comprised of discrete perchlorate anions and 2-amino-3-nitropyridinium cations. The anion has a typical tetrahedral geometry while the cation presents a nearly planar [maximum deviation = 0.007 (8) A ˚ ] pyridinium ring. Undulating [C5H6N3O2 +]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.
