The material described by Th3Rh is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Th sites. In the first Th site, Th(1) is bonded to four equivalent Th(1), four equivalent Th(2), and four equivalent Rh(1) atoms to form distorted ThTh8Rh4 cuboctahedra that share corners with twelve equivalent Th(1)Th8Rh4 cuboctahedra, edges with eight equivalent Th(1)Th8Rh4 cuboctahedra, edges with eight equivalent Rh(1)Th12 cuboctahedra, faces with four equivalent Rh(1)Th12 cuboctahedra, and faces with ten equivalent Th(1)Th8Rh4 cuboctahedra. In the second Th site, Th(2) is bonded in a square co-planar geometry to eight equivalent Th(1) and four equivalent Rh(1) atoms. Rh(1) is bonded to four equivalent Th(2) and eight equivalent Th(1) atoms to form RhTh12 cuboctahedra that share corners with four equivalent Rh(1)Th12 cuboctahedra, edges with eight equivalent Rh(1)Th12 cuboctahedra, edges with sixteen equivalent Th(1)Th8Rh4 cuboctahedra, faces with four equivalent Rh(1)Th12 cuboctahedra, and faces with eight equivalent Th(1)Th8Rh4 cuboctahedra. is represented by the CIF file [CIF]
