Bis[diethyl(hydroxy)ammonium] benzene-1,4-dicarboxylate

Abstract

In the centrosymmetric title compound, 2C4H12NO+·C8H4O42−, two N,N-diethyl(hydroxy)ammonium cations are linked to a benzene-1,4-dicarboxylate dianion by a combination of O—H...O and N—H...O hydrogen bonds, which can be described in graph-set terminology as R22(7). The crystal structure is further stabilized by C—H...O hydrogen bonds, leading to the fomation of a ribbon-like network.
