Materials Data on SiSbOs2 by Materials Project

Abstract

Os2SiSb crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Os+0.50- sites. In the first Os+0.50- site, Os+0.50- is bonded in a 4-coordinate geometry to four equivalent Os+0.50-, four equivalent Si4+, and six equivalent Sb3- atoms. All Os–Os bond lengths are 2.77 Å. All Os–Si bond lengths are 2.77 Å. All Os–Sb bond lengths are 3.20 Å. In the second Os+0.50- site, Os+0.50- is bonded in a 8-coordinate geometry to four equivalent Os+0.50-, six equivalent Si4+, and four equivalent Sb3- atoms. All Os–Si bond lengths are 3.20 Å. All Os–Sb bond lengths are 2.77 Å. Si4+ is bonded in a body-centered cubic geometry to ten Os+0.50- and four equivalent Sb3- atoms. All Si–Sb bond lengths are 2.77 Å. Sb3- is bonded in a distorted body-centered cubic geometry to ten Os+0.50- and four equivalent Si4+ atoms.
