Figure 2
The molecular configuration and atom-numbering scheme for the two 3-carboxyanilinium cations (B and D) and the two 2-carboxy-4,5-dichlorobenzoate anions (A and C) in the asymmetric unit of (II). Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. Dashed lines indicate inter-species hydrogen bonds. |
