Pyykkö, Chemical Reviews 1997, 97, 597-636). Here we highlight role of the HgII…HgII metalophillic attraction acting between the consecutive metal-mediated mismatched base pairs of nucleic acids. Usually, the base stacking dominates the non-covalent interactions between steps of native nucleic acids. In the presence of metal-mediated base pairs are these non-covalent interactions enriched by the metal-base interactions and the metalophillic attraction. The two interactions arising due to the metal linkage of the mismatches in this study were found to have a stabilizing effect on nucleic acid structure.
