Materials Data on TmSiIr by Materials Project
TmIrSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tm is bonded in a 11-coordinate geometry to six equivalent Ir and five equivalent Si atoms. There are a spread of Tm–Ir bond distances ranging from 2.98–3.22 Å. There are two shorter (2.89 Å) and three longer (2.97 Å) Tm–Si bond lengths. Ir is bonded in a 10-coordinate geometry to six equivalent Tm and four equivalent Si atoms. There are a spread of Ir–Si bond distances ranging from 2.47–2.58 Å. Si is bonded in a 9-coordinate geometry to five equivalent Tm and four equivalent Ir atoms.
