CeMnAl is Cubic Laves-derived structured and crystallizes in the orthorhombic Imma space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Ce(1), six equivalent Mn(1), and six equivalent Al(1) atoms. Mn(1) is bonded to six equivalent Ce(1), two equivalent Mn(1), and four equivalent Al(1) atoms to form MnCe6Mn2Al4 cuboctahedra that share corners with eight equivalent Al(1)Ce6Mn4Al2 cuboctahedra, corners with ten equivalent Mn(1)Ce6Mn2Al4 cuboctahedra, edges with six equivalent Mn(1)Ce6Mn2Al4 cuboctahedra, faces with six equivalent Mn(1)Ce6Mn2Al4 cuboctahedra, and faces with twelve equivalent Al(1)Ce6Mn4Al2 cuboctahedra. Al(1) is bonded to six equivalent Ce(1), four equivalent Mn(1), and two equivalent Al(1) atoms to form AlCe6Mn4Al2 cuboctahedra that share corners with eight equivalent Mn(1)Ce6Mn2Al4 cuboctahedra, corners with ten equivalent Al(1)Ce6Mn4Al2 cuboctahedra, edges with six equivalent Al(1)Ce6Mn4Al2 cuboctahedra, faces with six equivalent Al(1)Ce6Mn4Al2 cuboctahedra, and faces with twelve equivalent Mn(1)Ce6Mn2Al4 cuboctahedra.
CeMnAl is Cubic Laves-derived structured and crystallizes in the orthorhombic Imma space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Ce(1), six equivalent Mn(1), and six equivalent Al(1) atoms. There are two shorter (3.21 Å) and two longer (3.46 Å) Ce(1)-Ce(1) bond lengths. There are two shorter (3.05 Å) and four longer (3.24 Å) Ce(1)-Mn(1) bond lengths. There are four shorter (3.19 Å) and two longer (3.24 Å) Ce(1)-Al(1) bond lengths. Mn(1) is bonded to six equivalent Ce(1), two equivalent Mn(1), and four equivalent Al(1) atoms to form MnCe6Mn2Al4 cuboctahedra that share corners with eight equivalent Al(1)Ce6Mn4Al2 cuboctahedra, corners with ten equivalent Mn(1)Ce6Mn2Al4 cuboctahedra, edges with six equivalent Mn(1)Ce6Mn2Al4 cuboctahedra, faces with six equivalent Mn(1)Ce6Mn2Al4 cuboctahedra, and faces with twelve equivalent Al(1)Ce6Mn4Al2 cuboctahedra.
