摘要
Dilanthanum triniobium disulfide octaoxide, La2Nb3S2O8, crystallizes in the orthorhombic space group Pnnm and is isostructural with the Ln(2)Ta(3)X(2)O(8) (Ln=La, Ce, Pr and Nd, and X=S and Se) family of tantalum compounds. Nb4+ and Nb5+ ions co-exist in the structure and occupy different crystallographic sites. While the Nb4+ ions are found in mixed oxygen and sulfur octahedra, the Nb5+ ions are found in oxygen-only octahedra.
