A significant breakthrough in the nitride chemistry of main group elements has been achieved: Surprisingly Sn 3 N 4 , for which there had been no proof of existence until now, as well as the isotypic high‐pressure polymorphs γ ‐Si 3 N 4 and γ ‐Ge 3 N 4 have been synthesized. All three compounds crystallize in a spinel structure type (see picture) that previously has not been found for nitrides, and may have a high relevance for practical applications in the context of ultrahard materials.
