Pt3Rh is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Rh(1) is bonded to twelve equivalent Pt(1) atoms to form RhPt12 cuboctahedra that share corners with twelve equivalent Rh(1)Pt12 cuboctahedra, edges with twenty-four equivalent Pt(1)Pt8Rh4 cuboctahedra, faces with six equivalent Rh(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)Pt8Rh4 cuboctahedra. Pt(1) is bonded to four equivalent Rh(1) and eight equivalent Pt(1) atoms to form PtPt8Rh4 cuboctahedra that share corners with twelve equivalent Pt(1)Pt8Rh4 cuboctahedra, edges with eight equivalent Rh(1)Pt12 cuboctahedra, edges with sixteen equivalent Pt(1)Pt8Rh4 cuboctahedra, faces with four equivalent Rh(1)Pt12 cuboctahedra, and faces with fourteen equivalent Pt(1)Pt8Rh4 cuboctahedra.
