Piperidinium p-nitrobenzoate
Abstract
A new type of hydrogen-bond pattern for piperidinium p-substituted benzoates is reported; this is found in piperidinium p-nitrobenzoate, C5H12N+·C7H4NO4−, (I). In the crystal of (I), the cations and anions are linked by N—H⋯O hydrogen bonds around a center of symmetry to form a cyclic dimer of the formula unit.
