Figure 3
The molecular configuration and atom-numbering scheme for the 2-carboxyquinolinium cation, the 2-carboxy-4,5-dichlorobenzoate anion, the quinolinium-2-carboxylate adduct molecule and the water molecule of solvation in (III). Dashed lines indicate the interspecies hydrogen bonds. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. |
