KEu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. K(1) is bonded to twelve equivalent Eu(1) atoms to form KEu12 cuboctahedra that share corners with twelve equivalent K(1)Eu12 cuboctahedra, edges with twenty-four equivalent Eu(1)K4Eu8 cuboctahedra, faces with six equivalent K(1)Eu12 cuboctahedra, and faces with twelve equivalent Eu(1)K4Eu8 cuboctahedra. Eu(1) is bonded to four equivalent K(1) and eight equivalent Eu(1) atoms to form EuK4Eu8 cuboctahedra that share corners with twelve equivalent Eu(1)K4Eu8 cuboctahedra, edges with eight equivalent K(1)Eu12 cuboctahedra, edges with sixteen equivalent Eu(1)K4Eu8 cuboctahedra, faces with four equivalent K(1)Eu12 cuboctahedra, and faces with fourteen equivalent Eu(1)K4Eu8 cuboctahedra.
