化合物 Li4GeS4 已制备为透明、浅黄色湿敏晶体。 Li4GeS4 属于 Pnma 空间群，a = 14.107(6) Å、b = 7.770(3) Å 和 c = 6.162(2) Å。晶体结构通过直接法解析。 866 个观察到的反射的最终 R 和 Rw 值为 1.85 和 1.65%。 Li4GeS4 结构具有三个晶体学上独立的锂位点和一个锗位点。锂原子采用两种不同的配位类型。 Li 1 原子以方锥几何结构与五个硫原子配位，而Li 2 和Li 3 原子具有扭曲的四面体配位。 Ge 原子由四个硫原子以四面体配位，并被发现为 [GeS4]4- 单元。描述了 Li4GeS4 的各向异性三维晶体结构。
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 Rw-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 Li l 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.
