Figure 1
The structures and atom-numbering schemes for the His cation, IMP anion and solvent molecules joined by hydrogen bonds (dashed lines) in the asymmetric unit of (I). The intramolecular C8—H8⋯O5′ contact, stabilizing the IMP structure, is also shown. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. |
