The crystal structure described by UOs2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. U(1) is bonded in a 16-coordinate geometry to four equivalent U(1), three equivalent Os(1), and nine equivalent Os(2) atoms. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to six equivalent U(1) and six equivalent Os(2) atoms to form a mixture of face, corner, and edge-sharing OsU6Os6 cuboctahedra. In the second Os site, Os(2) is bonded to six equivalent U(1), two equivalent Os(1), and four equivalent Os(2) atoms to form a mixture of face, corner, and edge-sharing OsU6Os6 cuboctahedra. is represented by the CIF card [CIF]
