The structure described by Os2SiSb crystallizes in the cubic F-43m space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 14-coordinate geometry to four equivalent Os(2), four equivalent Si(1), and six equivalent Sb(1) atoms. In the second Os site, Os(2) is bonded in a 14-coordinate geometry to four equivalent Os(1), six equivalent Si(1), and four equivalent Sb(1) atoms. Si(1) is bonded in a body-centered cubic geometry to four equivalent Os(1), six equivalent Os(2), and four equivalent Sb(1) atoms. Sb(1) is bonded in a distorted body-centered cubic geometry to four equivalent Os(2), six equivalent Os(1), and four equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
