Materials Data on TbSiIr by Materials Project
TbIrSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tb is bonded in a 11-coordinate geometry to six equivalent Ir and five equivalent Si atoms. There are a spread of Tb–Ir bond distances ranging from 2.99–3.32 Å. There are two shorter (2.97 Å) and three longer (3.02 Å) Tb–Si bond lengths. Ir is bonded in a 10-coordinate geometry to six equivalent Tb and four equivalent Si atoms. There are a spread of Ir–Si bond distances ranging from 2.48–2.59 Å. Si is bonded in a 9-coordinate geometry to five equivalent Tb and four equivalent Ir atoms.
