Materials Data on CeSi2OsRu by Materials Project

Abstract

CeOsRuSi2 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. Ce3+ is bonded in a 8-coordinate geometry to eight equivalent Si4- atoms. All Ce–Si bond lengths are 3.24 Å. Os1+ is bonded to four equivalent Si4- atoms to form OsSi4 tetrahedra that share corners with four equivalent OsSi4 tetrahedra and edges with four equivalent RuSi4 tetrahedra. All Os–Si bond lengths are 2.40 Å. Ru4+ is bonded to four equivalent Si4- atoms to form RuSi4 tetrahedra that share corners with four equivalent RuSi4 tetrahedra and edges with four equivalent OsSi4 tetrahedra. All Ru–Si bond lengths are 2.40 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Ce3+, two equivalent Os1+, and two equivalent Ru4+ atoms.
