Mn3Rh is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mn(1) is bonded to eight equivalent Mn(1) and four equivalent Rh(1) atoms to form distorted MnMn8Rh4 cuboctahedra that share corners with twelve equivalent Mn(1)Mn8Rh4 cuboctahedra, edges with eight equivalent Rh(1)Mn12 cuboctahedra, edges with sixteen equivalent Mn(1)Mn8Rh4 cuboctahedra, faces with four equivalent Rh(1)Mn12 cuboctahedra, and faces with fourteen equivalent Mn(1)Mn8Rh4 cuboctahedra. Rh(1) is bonded to twelve equivalent Mn(1) atoms to form RhMn12 cuboctahedra that share corners with twelve equivalent Rh(1)Mn12 cuboctahedra, edges with twenty-four equivalent Mn(1)Mn8Rh4 cuboctahedra, faces with six equivalent Rh(1)Mn12 cuboctahedra, and faces with twelve equivalent Mn(1)Mn8Rh4 cuboctahedra.
