Figure 3
The S(5) ring motifs formed by intramolecular O—H⋯N hydrogen bonds involving the hydroxy groups and quinoline N atoms of the HqSA− anionic units. The intramolecular O—H⋯N hydrogen bonds are shown as dashed lines. The sheet structure of the HqSA− anionic units is formed by the planar intermolecular hydrogen-bond networks in the ab plane. The intermolecular O—H⋯O, C—H⋯O, O—H⋯N hydrogen bonds are also shown as dashed lines. [Symmetry codes: (i) x, y − 1, z; (ii) x − 1, y, z; (iii) x − 1, y − 1, z; (iv) x + 1, y, z.]. |
