Materials Data on TbSi2RuRh by Materials Project
TbRhRuSi2 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. Tb3+ is bonded in a distorted body-centered cubic geometry to eight equivalent Si4- atoms. All Tb–Si bond lengths are 3.17 Å. Ru2+ is bonded to four equivalent Si4- atoms to form RuSi4 tetrahedra that share corners with four equivalent RuSi4 tetrahedra and edges with four equivalent RhSi4 tetrahedra. All Ru–Si bond lengths are 2.39 Å. Rh3+ is bonded to four equivalent Si4- atoms to form RhSi4 tetrahedra that share corners with four equivalent RhSi4 tetrahedra and edges with four equivalent RuSi4 tetrahedra. All Rh–Si bond lengths are 2.39 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Tb3+, two equivalent Ru2+, two equivalent Rh3+, and one Si4- atom. The Si–Si bond length is 2.49 Å.
