HgII/AgI-mediated base pairs and their NMR spectroscopic studies

Modern nucleic acids chemistry enabled us to create various types of metal-mediated base pairs (metallo-base-pairs). Nowadays, their structural/spectroscopic data have been accumulated. From the NMR spectroscopic point of view, data on Hg II /Ag I -mediated base pairs are most accumulated. Accordingly, it would be informative to review a current state of the NMR spectroscopic data of the Hg II /Ag I -mediated base pairs for subsequent structural studies on other metallo-base-pairs.
