Materials Data on SnOs2Ru by Materials Project

Abstract

Os2RuSn crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Os2- sites. In the first Os2- site, Os2- is bonded in a distorted body-centered cubic geometry to four equivalent Os2- and four equivalent Sn2+ atoms. All Os–Os bond lengths are 2.75 Å. All Os–Sn bond lengths are 2.75 Å. In the second Os2- site, Os2- is bonded in a 8-coordinate geometry to four equivalent Os2-, four equivalent Ru2+, and six equivalent Sn2+ atoms. All Os–Ru bond lengths are 2.75 Å. All Os–Sn bond lengths are 3.17 Å. Ru2+ is bonded to four equivalent Os2- atoms to form distorted RuOs4 tetrahedra that share corners with twelve equivalent RuOs4 tetrahedra, corners with twelve equivalent SnOs10 tetrahedra, and faces with four equivalent SnOs10 tetrahedra. Sn2+ is bonded to ten Os2- atoms to form distorted SnOs10 tetrahedra that share corners with six equivalent SnOs10 tetrahedra, corners with twelve equivalent RuOs4 tetrahedra, faces with four equivalent RuOs4 tetrahedra, and faces with twelve equivalent SnOs10 tetrahedra.
