Inside the helix : In addition to hydrogen bonds and π stacking in natural DNA, metal‐ion‐mediated base pairing is a third key motif for the interaction between complementary DNA. The introduction of several metal‐ion‐mediated base pairs adjacent to each other in DNA allows the self‐assembled alignment of the metal centers to form a ferromagnetically coupled chain within the DNA‐like double helix (see picture).
