Crystal structure of piperidinium 4-nitrophenolate

Abstract

In the title molecular salt, C5H12N+·C6H4NO3−, the piperidine ring adopts a chair conformation and the cation is protonated at the N atom. In the anion, the nitro group is twisted at an angle of 10.30 (11)° with respect to the attached benzene ring. In the crystal, N—H...O hydrogen bonds link adjacent anions and cations into infinite chains propagating along [100]. The chains are linked by C—H...π interactions, forming sheets lying parallel to (001).
