2-Amino-4-methylpyridin-1-ium 2-(4-nitrophenyl)acetate

Abstract

In the title molecular salt, C6H9N2+·C8H6NO4−, the cation is protonated at its pyridine N atom. In the crystal, the anion and cation are connected by weak N—H...O hydrogen bonds, generating anR22(8) ring motif. A pair of N—H...O hydrogen bonds and a C—H...O contact generate anR23(19) ring motif. In the crystal, adjacent anions and cations are linked by N—H...O hydrogen bonds into infinite chains along [001]. The components are further linked by weak C—H...O contacts and C—H...π interactions, forming a three-dimensional network.
