Materials Data on RuRh3 by Materials Project

RuRh3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ru is bonded to twelve equivalent Rh atoms to form RuRh12 cuboctahedra that share corners with twelve equivalent RuRh12 cuboctahedra, edges with twenty-four equivalent RhRu4Rh8 cuboctahedra, faces with six equivalent RuRh12 cuboctahedra, and faces with twelve equivalent RhRu4Rh8 cuboctahedra. All Ru–Rh bond lengths are 2.72 Å. Rh is bonded to four equivalent Ru and eight equivalent Rh atoms to form RhRu4Rh8 cuboctahedra that share corners with twelve equivalent RhRu4Rh8 cuboctahedra, edges with eight equivalent RuRh12 cuboctahedra, edges with sixteen equivalent RhRu4Rh8 cuboctahedra, faces with four equivalent RuRh12 cuboctahedra, and faces with fourteen equivalent RhRu4Rh8 cuboctahedra. All Rh–Rh bond lengths are 2.72 Å.

Materials Data on RuRh3 by Materials Project

RuRh3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ru is bonded to twelve equivalent Rh atoms to form RuRh12 cuboctahedra that share corners with six equivalent RuRh12 cuboctahedra, corners with twelve equivalent RhRu4Rh8 cuboctahedra, edges with eighteen equivalent RhRu4Rh8 cuboctahedra, faces with eight equivalent RuRh12 cuboctahedra, and faces with twelve equivalent RhRu4Rh8 cuboctahedra. There are six shorter (2.69 Å) and six longer (2.74 Å) Ru–Rh bond lengths. Rh is bonded to four equivalent Ru and eight equivalent Rh atoms to form RhRu4Rh8 cuboctahedra that share corners with four equivalent RuRh12 cuboctahedra, corners with fourteen equivalent RhRu4Rh8 cuboctahedra, edges with six equivalent RuRh12 cuboctahedra, edges with twelve equivalent RhRu4Rh8 cuboctahedra, faces with four equivalent RuRh12 cuboctahedra, and faces with sixteen equivalent RhRu4Rh8 cuboctahedra. There are a spread of Rh–Rh bond distances ranging from 2.70–2.75 Å.
