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.
