Abstract

Black square plates of the new compound UEr ₂O ₂S ₃ have been synthesized by the reaction of UOS, Er, and S with an Sb ₂S ₃ flux at 1273 K. The structure of UEr ₂O ₂S ₃ has been solved and refined from single-crystal X-ray diffraction data. UEr ₂O ₂S ₃ forms a layered structure with layers of edge-sharing ErS ₆ octahedra and double layers of disordered (U/Er)O ₄S ₄ square antiprisms. Upon reexamination of the previously reported X-ray data for the U ^3.5 compound U ₂ErO ₂S ₃ we conclude that it also may be characterized as the U ⁴ compound UEr ₂O ₂S ₃.
