Remarkably Stable Chalcogen(II) Dications Academic Article uri icon


  • Air-stable, chalcogen-centered dications have been synthesized and comprehensively characterized. These represent the first diiminopyridine (DIMPY) complexes of the chalcogens as well as the single nonmetallic (sulfur) complex of this ubiquitous ligand. Their stability under ambient conditions is a distinct contrast to other highly charged main-group cations.
