2,2′-(Piperazine-1,4-diyl)diethanaminium dibenzoate
The asymmetric unit of the title salt C(8)H(22)N(4) (2+)·2C(7)H(5)O(2) (−), 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 wa...

Sumario: | The asymmetric unit of the title salt C(8)H(22)N(4) (2+)·2C(7)H(5)O(2) (−), 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 0-10 100 [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 [101]. 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. (2012 ▶). Acta Cryst, E68, o2387], the nitrate and the tetrahydrogen pentaborate salts. |
