Figure 7
A partial packing plot of II viewed down the b-axis showing a slice through the N—H⋯O (solid dashed lines) and O—H⋯O (open dashed lines) hydrogen-bonded double layers. Thin dashed lines indicate π–π stacking of cation and anion arene rings. Hydrogen atoms not participating in hydrogen bonds are omitted.
