The title salt, CHN·CHNO·HO, represents a pseudo-polymer ionic material, resulting from the self-organizing behavior of 4,4'-azinodibenzoate dianions and doubly protonated, 1,8-diaminium-octane cations in aqueous solution. The asymmetric unit consists of two halves of octane 1,8-diaminium cations (the complete cations are both generated by crystallographic inversion symmetry), a 4,4'-azinodibenzoate anion [dihedral angle between the aromatic rings = 10.22 (4)°] and a water mol-ecule of crystallization. One of the cations is in a fully extended linear conformation while the second one has a terminal C-C-C-N conformation. In the crystal, the cations, anions and water mol-ecules are linked into a three-dimensional network a complex pattern of charge-assisted N-H⋯O and O-H⋯O hydrogen bonds.
标题盐CHN·CHNO·HO代表一种准聚合物离子材料，它是由4,4'-偶氮二苯甲酸二价阴离子与双质子化的1,8-二氨基辛烷阳离子在水溶液中的自组装行为形成的。不对称单元由两个八烷1,8-二铵阳离子的一半组成（完整的阳离子均由晶体学反演对称性产生）、一个4,4'-偶氮二苯甲酸阴离子[芳环之间的二面角 = 10.22 (4)°]和一个结晶水分子。其中一个阳离子呈完全伸展的线性构象，而另一个具有末端C-C-C-N构象。在晶体中，阳离子、阴离子和水分子通过电荷辅助的N-H⋯O和O-H⋯O氢键连接成三维网络，呈现出复杂的模式。
