Materials Data on USiRu by Materials Project

Abstract

URuSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. U is bonded in a 11-coordinate geometry to two equivalent U, four equivalent Ru, and five equivalent Si atoms. Both U–U bond lengths are 2.85 Å. There are three shorter (2.96 Å) and one longer (3.06 Å) U–Ru bond lengths. There are a spread of U–Si bond distances ranging from 2.89–3.04 Å. Ru is bonded in a 8-coordinate geometry to four equivalent U and four equivalent Si atoms. There are three shorter (2.46 Å) and one longer (2.47 Å) Ru–Si bond lengths. Si is bonded in a 9-coordinate geometry to five equivalent U and four equivalent Ru atoms.
