Materials Data on ScSiIr by Materials Project
ScIrSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sc is bonded in a 11-coordinate geometry to six equivalent Ir and five equivalent Si atoms. There are a spread of Sc–Ir bond distances ranging from 2.90–3.07 Å. There are a spread of Sc–Si bond distances ranging from 2.80–2.88 Å. Ir is bonded in a 10-coordinate geometry to six equivalent Sc and four equivalent Si atoms. There are three shorter (2.46 Å) and one longer (2.49 Å) Ir–Si bond lengths. Si is bonded in a 9-coordinate geometry to five equivalent Sc and four equivalent Ir atoms.
