Rh3Fe is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Fe(1) is bonded to twelve equivalent Rh(1) atoms to form FeRh12 cuboctahedra that share corners with six equivalent Fe(1)Rh12 cuboctahedra, corners with twelve equivalent Rh(1)Fe4Rh8 cuboctahedra, edges with eighteen equivalent Rh(1)Fe4Rh8 cuboctahedra, faces with eight equivalent Fe(1)Rh12 cuboctahedra, and faces with twelve equivalent Rh(1)Fe4Rh8 cuboctahedra. Rh(1) is bonded to four equivalent Fe(1) and eight equivalent Rh(1) atoms to form distorted RhFe4Rh8 cuboctahedra that share corners with four equivalent Fe(1)Rh12 cuboctahedra, corners with fourteen equivalent Rh(1)Fe4Rh8 cuboctahedra, edges with six equivalent Fe(1)Rh12 cuboctahedra, edges with twelve equivalent Rh(1)Fe4Rh8 cuboctahedra, faces with four equivalent Fe(1)Rh12 cuboctahedra, and faces with sixteen equivalent Rh(1)Fe4Rh8 cuboctahedra.
