We do not report details about other screened cations because our exploratory calculations suggest that they do not feature the localized transitions. Cations of Cr or Mo with a C or Si have very different electronic structure with significant multi-configurational character and their dications do not converge to a closed-shell singlet state. We detected similar problems for Ti or Zr with Se cations as well as V and Nb with As cations. This is not surprising, as transition metals with more than three d-electrons are known to result in complicated multi-configurational structure and dense manifolds of electronic states.
