Figure 1
The molecular structure of the 2′,3′-cAMP⁻ (left) and 2′,3′-cGMP⁻ (right) anions in (I)

and (II)

, respectively, showing the atom-numbering schemes and the intramolecular C—H⋯N hydrogen bond in (II)

(marked with a dashed line). Displacement ellipsoids are drawn at the 20% probability level for the non-H atoms.
