(a) cIMP−–Na layers in (V) stabilized by π–π stacking interactions (dotted lines) and (b) hydrogen bonds (dashed lines) formed between two layers (shown in yellow and grey). Nucleotide H atoms and noncoordinated water molecules in (a) have been omitted for clarity. H atoms not involved in hydrogen bonds in (b) are not shown. The symmetry codes are as given in Table 10. |
