| Abstract: | The crystal structure of samarium monothio sulfide, was solved using single crystal refined data. Sm2O2S, crystallizes in the trigonal system with space group P m1 (no. 164), Z=1 and cell constants a=388.7(1) pm and c=670.9(3) pm. The discrepancy indices of the single crystal structure refinement were R1=0.031 and wR2=0.077. Sm2O2S is isostructural with M2O2S (M=La, Ce, Nd, and Tm). The structure can be described as a packing of S−2 and O−2 anions with Sm+3 located in the center of a capped octahedron in which the seventh ligand (an oxygen atom) has been added to the triangular face formed only by O atoms. |
