Resumen: Metal ions are natural counterparts of nucleic acids and crucial in stabilizing many specific structures. While the relevant bulk main group metal ions (Na+, K+, Mg2+) are predominantly important in keeping base pairs in register and/or allowing the formation of particular specific RNA structures, transition metal ions, and specifically the soft ones, display a pronounced affinity for donor atoms of the heterocyclic nucleobases as part of nucleic acids. Their nature in fact provides a large number of different binding patterns, including specific cross-links and/or the formation of cyclic entities and/or cages. This review article summarizes constructs obtained this way, without over-emphasizing their biological relevance. Nevertheless, it can be claimed that in a number of cases model findings have preceded their discoveries in biorelevant events.
