The asymmetric unit of the title salt, C(8)H(22)N(4) (2+)·2C(7)H(5)O(3) (-), comprises half a 2,2'-(piperazine-1,4-di-yl)diethan-aminium dication plus a 2-hy-droxy-benzoate 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 the a unit-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 tetra-hydrogen penta-borate salts.
标题盐C(8)H(22)N(4)(2+)·2C(7)H(5)O(3)(-)的不对称单元包含半个2,2'-（哌嗪-1,4-二基）二乙铵双阳离子和一个2-羟基苯甲酸根阴离子。在晶体中，阴离子和阳离子通过N-H⋯O和O-H⋯O氢键相连，形成与a晶胞面平行的无限二维网络。晶体中阳离子所采用的构象与该阳离子在硝酸盐和四氢五硼酸盐结构中所采用的构象非常相似。
