Black square plates of the new compound UEr2O2S3 have been synthesized by the reaction of UOS, Er, and S with an Sb2S3 flux at 1273 K. The structure of UEr2O2S3 has been solved and refined from single-crystal X-ray diffraction data. UEr2O2S3 forms a layered structure with layers of edge-sharing ErS6 octahedra and double layers of disordered (U/Er)O4S4 square antiprisms. Upon reexamination of the previously reported X-ray data for the U3.5+ compound U2ErO2S3 we conclude that it also may be characterized as the U4+ compound UEr2O2S3.
