The compound described by W2Os is beta Uranium-derived structured and crystallizes in the tetragonal P4_2/mnm space group. There are three inequivalent W sites. In the first W site, W(1) is bonded in a 15-coordinate geometry to one W(1), two equivalent W(2), six equivalent W(3), two equivalent Os(1), and four equivalent Os(2) atoms. In the second W site, W(2) is bonded in a 6-coordinate geometry to one W(1), one W(2), and four equivalent Os(2) atoms. In the third W site, W(3) is bonded in a 7-coordinate geometry to two equivalent W(3), three equivalent W(1), one Os(1), and four equivalent Os(2) atoms. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to four equivalent W(1), four equivalent W(3), and four equivalent Os(2) atoms to form OsOs4W8 cuboctahedra that share corners with sixteen equivalent Os(2)Os2W10 cuboctahedra, edges with two equivalent Os(1)Os4W8 cuboctahedra, and faces with four equivalent Os(2)Os2W10 cuboctahedra. In the second Os site, Os(2) is bonded to two equivalent W(1), four equivalent W(2), four equivalent W(3), one Os(1), and one Os(2) atom to form OsOs2W10 cuboctahedra that share corners with four equivalent Os(1)Os4W8 cuboctahedra, corners with seven equivalent Os(2)Os2W10 cuboctahedra, edges with three equivalent Os(2)Os2W10 cuboctahedra,  a faceface with one Os(1)Os4W8 cuboctahedra, and faces with six equivalent Os(2)Os2W10 cuboctahedra. is represented by the CIF file [CIF]
