Popis: |
Rare earth fluorosulfides with the following compositions: LnSF and Ln 2 AF 4 S 2 have been prepared by solid state routes. These structures can be described as a stacking of fluoride-based slabs ([Ln 2 F 2 ] 4+ in LnSF and [Ln 2 AF 4 ] 4+ in Ln 2 AF 4 S 2 ) and double layers [S 2 ] 4− . The fluoride blocks are related to fluorite-type structure. The relative compactness of the fluoride blocks leads to a relaxation of the LnS bond lengths. |
