Abstract

We briefly surveyed metal‐rich and intermetallic compounds containing metal anions that have been characterized by density functional calculations. Transition metal anions come with electron configurations (n+1)s^2^__n__d^10^(n+1)p^0^, (n+1)s^2^__n__d^10^(n+1)p^1^, and (n+1)s^2^__n__d^10^(n+1)p^2^. Their __n__d orbitals act asreservoirs for holding ten electrons. Thus, these anions exhibit bonding characteristics similar to those found for their main group analogues.
