Understanding the alkali – Germanium interaction in the ternary Zintl phase Li18Na2Ge17: First-principles study
The Zintl ternary phase, Li18Na2Ge17, have been synthesized typically from a very electropositive metals (Ge) and more electronegative main group metals Na and Li. We attempted to understand its
Homoatomic Polyanions of the Early p-Block Elements
This article reviews the chemistry of homoatomic polyanions of the early p-block elements (groups 13–15). The focus is on species that have been structurally authenticated in solid-state compounds
Li18Na2Ge17--a compound demonstrating cation effects on cluster shapes and crystal packing in ternary Zintl phases.
TLDR
The novel ternary Zintl phase Li18Na2Ge17 was synthesized from a stoichiometric melt and characterized crystallographically and experimentally verified by its diamagnetism, demonstrating the great effects that cations exert on such ZintL phases through optimized cluster sheathing and space filling.

TLDR
Synthetic explorations have now established that many of the clusters can in fact be obtained from neat (solvent free) high-temperature reactions of binary to quaternary systems, particularly for the heavier tetrel and triel elements.
