Rh3Ta is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ta(1) is bonded to twelve equivalent Rh(1) atoms to form TaRh12 cuboctahedra that share corners with twelve equivalent Ta(1)Rh12 cuboctahedra, edges with twenty-four equivalent Rh(1)Ta4Rh8 cuboctahedra, faces with six equivalent Ta(1)Rh12 cuboctahedra, and faces with twelve equivalent Rh(1)Ta4Rh8 cuboctahedra. Rh(1) is bonded to four equivalent Ta(1) and eight equivalent Rh(1) atoms to form distorted RhTa4Rh8 cuboctahedra that share corners with twelve equivalent Rh(1)Ta4Rh8 cuboctahedra, edges with eight equivalent Ta(1)Rh12 cuboctahedra, edges with sixteen equivalent Rh(1)Ta4Rh8 cuboctahedra, faces with four equivalent Ta(1)Rh12 cuboctahedra, and faces with fourteen equivalent Rh(1)Ta4Rh8 cuboctahedra.
