Without problems and from “within”, that is, by Li–As multicenter bonds and LiHC interactions, is the description of how the electronic stabilization of the Li atoms appears to function in the Ge2As6Li6 framework of 1, which is shielded by bulky tBu and SiiPr3 substituents. The lithium-rich main group element aggregate 1 is formed in the reaction of tBuGeF3 with LiAs(SiiPr3)H in the presence of tBuLi. • As, Ge, ◯Li, ⊗ R1 SiiPr3, ⊙ R2 tBu.
