CeFeCu is Hexagonal Laves-derived structured and crystallizes in the orthorhombic Imma space group. Ce(1) is bonded in a 12-coordinate geometry to six equivalent Fe(1) and six equivalent Cu(1) atoms. Fe(1) is bonded to six equivalent Ce(1), two equivalent Fe(1), and four equivalent Cu(1) atoms to form FeCe6Fe2Cu4 cuboctahedra that share corners with eight equivalent Cu(1)Ce6Fe4Cu2 cuboctahedra, corners with ten equivalent Fe(1)Ce6Fe2Cu4 cuboctahedra, edges with six equivalent Fe(1)Ce6Fe2Cu4 cuboctahedra, faces with six equivalent Fe(1)Ce6Fe2Cu4 cuboctahedra, and faces with twelve equivalent Cu(1)Ce6Fe4Cu2 cuboctahedra. Cu(1) is bonded to six equivalent Ce(1), four equivalent Fe(1), and two equivalent Cu(1) atoms to form CuCe6Fe4Cu2 cuboctahedra that share corners with eight equivalent Fe(1)Ce6Fe2Cu4 cuboctahedra, corners with ten equivalent Cu(1)Ce6Fe4Cu2 cuboctahedra, edges with six equivalent Cu(1)Ce6Fe4Cu2 cuboctahedra, faces with six equivalent Cu(1)Ce6Fe4Cu2 cuboctahedra, and faces with twelve equivalent Fe(1)Ce6Fe2Cu4 cuboctahedra.
CeFeCu is Hexagonal Laves-derived structured and crystallizes in the orthorhombic Imma space group. Ce(1) is bonded in a 12-coordinate geometry to six equivalent Fe(1) and six equivalent Cu(1) atoms. There are four shorter (2.96 Å) and two longer (3.07 Å) Ce(1)-Fe(1) bond lengths. There are four shorter (3.02 Å) and two longer (3.15 Å) Ce(1)-Cu(1) bond lengths. Fe(1) is bonded to six equivalent Ce(1), two equivalent Fe(1), and four equivalent Cu(1) atoms to form FeCe6Fe2Cu4 cuboctahedra that share corners with eight equivalent Cu(1)Ce6Fe4Cu2 cuboctahedra, corners with ten equivalent Fe(1)Ce6Fe2Cu4 cuboctahedra, edges with six equivalent Fe(1)Ce6Fe2Cu4 cuboctahedra, faces with six equivalent Fe(1)Ce6Fe2Cu4 cuboctahedra, and faces with twelve equivalent Cu(1)Ce6Fe4Cu2 cuboctahedra. Both Fe(1)-Fe(1) bond lengths are 2.61 Å. All Fe(1)-Cu(1) bond lengths are 2.61 Å. Cu(1) is bonded to six equivalent Ce(1), four equivalent Fe(1), and two equivalent Cu(1) atoms to form CuCe6Fe4Cu2 cuboctahedra that share corners with eight equivalent Fe(1)Ce6Fe2Cu4 cuboctahedra, corners with ten equivalent Cu(1)Ce6Fe4Cu2 cuboctahedra, edges with six equivalent Cu(1)Ce6Fe4Cu2 cuboctahedra, faces with six equivalent Cu(1)Ce6Fe4Cu2 cuboctahedra, and faces with twelve equivalent Fe(1)Ce6Fe2Cu4 cuboctahedra.
