4-Carbamoylpiperidinium 5-nitro­salicylate

摘要

In the crystal structure of the title compound, C6H13N2O⁺·C7H4NO5 ⁻, the isonipecotamide cations and the 5-nitro­salicylate anions form hydrogen-bonded chain substructures through head-to-tail piperidinium–carboxyl­ate N—H⋯O hydrogen bonds and through centrosymmetric cyclic head-to-head amide–amide hydrogen-bonding associations [graph set R 2 ²(8)]. These chains are cross-linked by amide–carboxyl­ate N—H⋯O and piperidinium–nitro N—H⋯O associations, giving a sheet structure.
