Variations on nature : Coordinative metal–ligand bonds instead of cyclic hydrogen bonds, an anion (sulfate) in the center rather than a cation, and an overall positive charge instead of a negative one are the major differences between the artificial platinum–purine quartet 2 (left) and the naturally occurring guanine quartet G 4 (right).
