Piperidinium 3-hydroxy-2-naphthoate

Abstract

The crystals of the title salt, C5H12N+·C11H7O3−, were obtained from a methanol/water solution of 3-hydroxy-2-naphthoic acid and piperidine at room temperature. In the crystal structure, the piperidinium cations display a chair conformation and link with hydroxynaphthoate anions via N—H...O and C—H...O hydrogen bonds. An intramolecular O—H...O interaction is also present.
