2-Amino-5-chloropyridinium salicylate

Abstract

In the crystal structure of the title salt, C5H 6ClN2+·C7H5O 3-, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms via a pair of N - H⋯O hydrogen bonds, forming R22(8) ring motifs. These motifs are centrosymmetrically paired via N - H⋯O hydrogen bonds, forming a complementary donor-donor-acceptor-acceptor (DDAA) array. A typical intra-molecular O - H⋯O hydrogen bond is also observed in the salicylate anion. The crystal structure is further stabilized by weak C - H⋯π inter-actions.
