4,4′-Trimethylenedipiperidiniumbenzene-1,4-dicarboxylate

Abstract

The hydro­thermal reaction of benzene-1,4-dicarboxylic acid and 4,4′-trimethyl­ene dipiperidine leads to the formation of the title compound, C13H28N2 2+·C8H4O4 2−. The anion is located on a center of inversion whereas the cation is positioned on a twofold rotation axis. In the crystal structure, the anions and cations are linked by N—H⋯O and N—H⋯(O,O) hydrogen bonds.
