2,2′-(Piperazine-1,4-diyl)diethanaminium bis(2-hydroxybenzoate)

Abstract

The asymmetric unit of the title salt, C8H22N42+·2C7H5O3−, comprises half a 2,2′-(piperazine-1,4-diyl)diethanaminium dication plus a 2-hydroxybenzoate anion. In the crystal, the anions and cations are linked by N—H...O and O—H...O hydrogen bonds to form infinite two-dimensional networks parallel with theaunit-cell face. The conformation adopted by the cation in the crystal is very similar to that adopted by the same cation in the structures of the nitrate and tetrahydrogen pentaborate salts.
