RuZr is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Zr is bonded in a body-centered cubic geometry to eight equivalent Ru atoms. All Zr–Ru bond lengths are 2.84 Å. Ru is bonded in a body-centered cubic geometry to eight equivalent Zr atoms.
Ru2Zr is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Zr is bonded in a 12-coordinate geometry to twelve Ru atoms. There are a spread of Zr–Ru bond distances ranging from 3.04–3.08 Å. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded to six equivalent Zr and six equivalent Ru atoms to form a mixture of corner, edge, and face-sharing RuZr6Ru6 cuboctahedra. All Ru–Ru bond lengths are 2.65 Å. In the second Ru site, Ru is bonded to six equivalent Zr and six Ru atoms to form a mixture of corner, edge, and face-sharing RuZr6Ru6 cuboctahedra. There are two shorter (2.52 Å) and two longer (2.68 Å) Ru–Ru bond lengths.
ZrRu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Zr is bonded to twelve equivalent Ru atoms to form a mixture of corner and face-sharing ZrRu12 cuboctahedra. All Zr–Ru bond lengths are 2.81 Å. Ru is bonded in a distorted square co-planar geometry to four equivalent Zr atoms.
ZrRu3 is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Zr is bonded to twelve equivalent Ru atoms to form a mixture of face and corner-sharing ZrRu12 cuboctahedra. There are six shorter (2.79 Å) and six longer (2.86 Å) Zr–Ru bond lengths. Ru is bonded in a distorted see-saw-like geometry to four equivalent Zr atoms.
