Materials Data on TbSiRh by Materials Project
TbRhSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tb is bonded in a 5-coordinate geometry to five equivalent Rh and six equivalent Si atoms. There are a spread of Tb–Rh bond distances ranging from 2.88–3.01 Å. There are a spread of Tb–Si bond distances ranging from 3.16–3.29 Å. Rh is bonded in a 9-coordinate geometry to five equivalent Tb and four equivalent Si atoms. All Rh–Si bond lengths are 2.58 Å. Si is bonded to six equivalent Tb, four equivalent Rh, and two equivalent Si atoms to form a mixture of distorted face, edge, and corner-sharing SiTb6Si2Rh4 cuboctahedra. Both Si–Si bond lengths are 2.59 Å.
