A Series of Mixed‐Metal Borohydrides

Abstract

Mix and match: A novel series of alkali-metal zinc borohydrides, LiZn2(BH4)5 (see picture), NaZn2(BH4)5, and NaZn(BH4)3, with fascinating structures are presented. An interpenetrated network structure, containing a [Zn2(BH4)5]− ion, is observed for the first time for a borohydride. A three-dimensional framework containing a polymeric [{Zn(BH4)3}n]n− ion is also identified.
