The material described by Eu3Nd is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Eu(1) is bonded to eight equivalent Eu(1) and four equivalent Nd(1) atoms to form EuNd4Eu8 cuboctahedra that share corners with four equivalent Nd(1)Eu12 cuboctahedra, corners with fourteen equivalent Eu(1)Nd4Eu8 cuboctahedra, edges with six equivalent Nd(1)Eu12 cuboctahedra, edges with twelve equivalent Eu(1)Nd4Eu8 cuboctahedra, faces with four equivalent Nd(1)Eu12 cuboctahedra, and faces with sixteen equivalent Eu(1)Nd4Eu8 cuboctahedra. Nd(1) is bonded to twelve equivalent Eu(1) atoms to form NdEu12 cuboctahedra that share corners with six equivalent Nd(1)Eu12 cuboctahedra, corners with twelve equivalent Eu(1)Nd4Eu8 cuboctahedra, edges with eighteen equivalent Eu(1)Nd4Eu8 cuboctahedra, faces with eight equivalent Nd(1)Eu12 cuboctahedra, and faces with twelve equivalent Eu(1)Nd4Eu8 cuboctahedra. is represented by the CIF file [CIF]
