Abstract : Work was focused on the characterization of the rare-earth-rhenium compounds and a new compound of samarium. Precise unit cell data are reported for Yb2ReO5, Er2ReO5, and Dy2ReO5. Nd2ReO5 is polymorphic and cell data for both forms are reported. The results of a large sequence of experiments are reported in which compound formation was sought between ReO2 and MgO, CdO, Sb2O3, Al2O3, Cr2O3, and Fe2O3. The samarium compound tentatively identified as Sm3O4 is now thought to be a silicate 2 Sm2O3.SiO2. (Author)
