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).
