Abstract

In the crystal structure of the title compound, C8H26N44+center dot-2C(4)O(4)(2-), the bis(3-ammoniopropyl) ethylenediaminium (PAED) cation lies on an inversion centre and the squarate anion (Sq(2-)) is in a general position. Salt formation occurs by donation of four H atoms from two squaric acid molecules to the bis(3-aminopropyl) ethylenediamine base. In the crystal structure, the strongest interactions are between H atoms of NH2+ groups and squarate O atoms. All the H atoms of NH3+ groups of the PAED cation also participate in hydrogen bonding with the O atoms of the Sq(2-) anion, contributing to the crystal packing.
