GdPS为正交结构,空间群Pmnb;= 5.3620 (5), b = 5.4079 (6), c = 16.742(2)一个,Z = 8。它是四边形pbcl结构(a 0, c 0)的畸变导数,a≈b≈2 1 2 a 0, c= 2c 0。扭曲是由于磷链的形成。这种结构类型也存在于其他稀土硫聚磷酸酯中,如Ln= La··Sm, Tb··Tm, Y。
The structure of GdPS is orthorhombic, space group Pmnb; a= 5.3620 (5), b= 5.4079 (6), c= 16.742 (2) Å, Z= 8. It is a distorted derivative of the tetragonal PbFCl structure (a 0, c 0) with a≈ b≈ 2 1 2 a 0, c= 2c 0. The distortions are due to the formation of phosphorus chains. This structure type is found also in other rare-earth sulfopolyphosphides, eg, with Ln= La··· Sm, Tb··· Tm, Y.
