Refinement of the crystal structure of UOswas performed for the first time by using single-crystal X-ray diffraction data, which allowed the refinement of allterms of the displacement parameters. toc Single crystals of uranium diosmium, UOs, were obtained during an investigation of the uranium-osmium binary system by an inter­action of uranium metal with osmium metal in an arc furnace and subsequent annealing. The refinement of the crystal structure of UOwas carried out for the first time using single-crystal X-ray diffraction data. In contrast to previous structure reports based on powder diffraction data, the U and Os atoms were refined with allterms of the displacement parameters considered. UOsadopts the MgCustructure type.
