Non-existent Zn-Zn double bonds computationally predicted.


While double bonds are known for transition metals of groups 9 and 10, as well as for boron and p-block elements of groups 14-16, Zn sits in a small region of the periodic table with no well characterized double bonds. A qualitative reasoning indicates that zerovalent Zn has the potential for forming Zn=Zn double bonds. The computational work presented in this paper provides support for such a proposal.
