Figure 3
The molecular conformation and atom-numbering scheme for the 4-(aminocarbonyl)pyridinium cation, the 2-carboxy-4,5-dichlorobenzoate anion and the methyl 2-carboxy-4,5-dichlorobenzoate adduct molecule in (III). The dashed lines indicate the inter-species hydrogen bonds, while non-H atoms are shown as 50% probability displacement ellipsoids. |
