TbRu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tb is bonded to twelve equivalent Ru atoms to form a mixture of face and corner-sharing TbRu12 cuboctahedra. All Tb–Ru bond lengths are 2.87 Å. Ru is bonded in a distorted square co-planar geometry to four equivalent Tb atoms.
Tb3Ru is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 2-coordinate geometry to three equivalent Ru atoms. There are a spread of Tb–Ru bond distances ranging from 2.86–3.26 Å. In the second Tb site, Tb is bonded in a distorted bent 150 degrees geometry to two equivalent Ru atoms. There are one shorter (2.77 Å) and one longer (2.80 Å) Tb–Ru bond lengths. Ru is bonded in a 6-coordinate geometry to eight Tb atoms.
TbRu2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tb is bonded in a 12-coordinate geometry to twelve Ru atoms. There are a spread of Tb–Ru bond distances ranging from 3.10–3.21 Å. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded to six equivalent Tb and six equivalent Ru atoms to form a mixture of face, edge, and corner-sharing RuTb6Ru6 cuboctahedra. All Ru–Ru bond lengths are 2.74 Å. In the second Ru site, Ru is bonded to six equivalent Tb and six Ru atoms to form a mixture of face, edge, and corner-sharing RuTb6Ru6 cuboctahedra. There are two shorter (2.56 Å) and two longer (2.71 Å) Ru–Ru bond lengths.
