Materials Data on U3Al3NiRu2 by Materials Project

Abstract

U3Ru2NiAl3 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. U is bonded in a 5-coordinate geometry to four equivalent Ru, one Ni, and six equivalent Al atoms. All U–Ru bond lengths are 2.86 Å. The U–Ni bond length is 2.89 Å. There are two shorter (3.11 Å) and four longer (3.19 Å) U–Al bond lengths. Ru is bonded in a 9-coordinate geometry to six equivalent U and three equivalent Al atoms. All Ru–Al bond lengths are 2.71 Å. Ni is bonded in a 9-coordinate geometry to three equivalent U and six equivalent Al atoms. All Ni–Al bond lengths are 2.55 Å. Al is bonded in a 4-coordinate geometry to six equivalent U, two equivalent Ru, and two equivalent Ni atoms.
