Abstract

The compound Li₄GeS₄ has been prepared as transparent, light yellow moisture-sensitive crystals. Li₄GeS₄ belongs to the space group Pnma with a = 14.107(6) Å b = 7.770(3) Å and c = 6.162(2) Å. The crystal structure was solved by direct-methods. The final R and R_w-values are 1.85 and 1.65% for 866 observed reflections. The Li₄GeS₄ structure has three crystallographically independent lithium sites and one germanium site. The lithium atoms adopt two different coordination types. The Li1 atom is coordinated to five sulfur atoms in a square pyramidal geometry, while the Li2 and Li3 atoms have distorted tetrahedral coordination. The Ge atom is tetrahedrally coordinated by four sulfur atoms and is found as [GeS₄]^4- units. The anisotropic three-dimensional crystal structure of Li₄GeS₄ is described.
