The inter-action between 8-hy-droxy-quinoline (8HQ, CHNO) and naphthalene-1,5-di-sulfonic acid (HNDS, CHOS) in aqueous media results in the formation of the salt hydrate bis-(8-hy-droxy-quinolinium) naphthalene-1,5-di-sulfonate tetra-hydrate, 2CHNO·CHOS ·4HO. The asymmetric unit comprises one protonated 8HQ cation, half of an NDS dianion symmetrically disposed around a center of inversion, and two water mol-ecules. Within the crystal structure, these components are organized into chains along the [010] and [10] directions through O-H⋯O and N-H⋯O hydrogen-bonding inter-actions, forming a di-periodic network parallel to (101). Additional stabilizing inter-actions such as C-H⋯O, C-H⋯π, and π-π inter-actions extend this arrangement into a tri-periodic network structure.
8-羟基喹啉（8HQ，C₉H₇NO）与萘-1,5-二磺酸（HNDS，C₁₀H₆O₆S₂）在水介质中的相互作用导致形成盐水合物双-(8-羟基喹啉鎓)萘-1,5-二磺酸盐四水合物，2C₉H₇NO·C₁₀H₆O₆S₂·4H₂O。不对称单元包括一个质子化的8HQ阳离子、围绕一个反演中心对称排列的半个NDS二价阴离子以及两个水分子。在晶体结构中，这些组分通过O-H⋯O和N-H⋯O氢键相互作用沿[010]和[10]方向组织成链，形成平行于(101)的二维网络。诸如C-H⋯O、C-H⋯π和π-π相互作用等额外的稳定相互作用将这种排列扩展为三维网络结构。
