Abstract: In the title compound, [Ni(HQS)(H₂O)₄]·H₂O (HQS is the 8-hydroxyquinoline-5-sulfonic acid dianion, C₉H₁₃NO₈S), the Ni^II ion is coordinated by the N and quinolinolate-O atoms of HQS and four water molecules, exhibiting a distorted octahedral geometry. The sulfonic O atoms of HQS are not involved in the coordination. However, the sulfonic O atoms along with the coordinated and lattice water molecules play a vital role in assembling the three-dimensional structure by an extensive network of intermolecular O-HO hydrogen bonds. Furthermore, the overall structure is stabilized by - stacking interactions between the ring moieties of HQS in the neighbouring complex molecules.
