The asymmetric unit of the title salt C8H22N4
comprises two independent pairs of half a 2,2'-(piperazine-1,4-
diyl)diethanaminium dication plus a benzoate anion. The
dications are symmetrical and lie across crystallographic
centres of inversion. The crystal structure was refined as a
two-component pseudo-merohedral twin using the twin law
001 010 100 [he domain fractions are 0.8645 (8) and
0.1355 (8)]. The anions and cations are linked by N—H...O
hydrogen bonds and weak N—H...O intermolecular interactions
to form infinite two-dimensional networks parallel to
. The conformation adopted by the cation in the crystal
structure is very similar to that adopted by the same cation in
the structures of the 2-hydroxybenzoate [Cukrowski et al.
