Abstract
A novel quaternary Zintl phase of silicon is presented. The crystal structu re of Ba6Mg10.8Li1.2Si12 (Pnma, a = 22.257(5), b = 4.5804(9), c = 14.007(3) Angstrom) is the first example of a silicide with isolated silicon atoms, Si-2 dumb-bells and Si-3 chains thus with three different Zintl anions with in one structure. Accompanying quantumchemical investigations in the Extend ed Huckel framework give detailed insights in the present bond situation an d support general trends found in unusual Zintl phases.
