LuRu is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Lu is bonded in a body-centered cubic geometry to eight equivalent Ru atoms. All Lu–Ru bond lengths are 2.89 Å. Ru is bonded in a body-centered cubic geometry to eight equivalent Lu atoms.
LuRu2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Lu is bonded in a 12-coordinate geometry to twelve Ru atoms. There are a spread of Lu–Ru bond distances ranging from 3.07–3.15 Å. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded to six equivalent Lu and six equivalent Ru atoms to form a mixture of corner, edge, and face-sharing RuLu6Ru6 cuboctahedra. All Ru–Ru bond lengths are 2.70 Å. In the second Ru site, Ru is bonded to six equivalent Lu and six Ru atoms to form a mixture of corner, edge, and face-sharing RuLu6Ru6 cuboctahedra. There are two shorter (2.54 Å) and two longer (2.69 Å) Ru–Ru bond lengths.
LuRu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Lu is bonded to twelve equivalent Ru atoms to form a mixture of corner and face-sharing LuRu12 cuboctahedra. All Lu–Ru bond lengths are 2.84 Å. Ru is bonded in a distorted square co-planar geometry to four equivalent Lu atoms.
