Materials Data on U(Al5Ru)2 by Materials Project
URu2Al10 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. U is bonded in a 10-coordinate geometry to four equivalent Ru and sixteen Al atoms. All U–Ru bond lengths are 3.45 Å. There are a spread of U–Al bond distances ranging from 3.15–3.63 Å. Ru is bonded in a 10-coordinate geometry to two equivalent U and ten Al atoms. There are a spread of Ru–Al bond distances ranging from 2.58–2.74 Å. There are five inequivalent Al sites. In the first Al site, Al is bonded in a distorted linear geometry to two equivalent U and two equivalent Ru atoms. In the second Al site, Al is bonded in a 2-coordinate geometry to one U and two equivalent Ru atoms. In the third Al site, Al is bonded in a distorted bent 120 degrees geometry to two equivalent U and two equivalent Ru atoms. In the fourth Al site, Al is bonded in a distorted bent 120 degrees geometry to two equivalent U and two equivalent Ru atoms. In the fifth Al site, Al is bonded in a 12-coordinate geometry to one U and two equivalent Ru atoms.
