YMnAl is Hexagonal Laves-derived structured and crystallizes in the orthorhombic Imma space group. Y(1) is bonded in a 16-coordinate geometry to four equivalent Y(1), six equivalent Mn(1), and six equivalent Al(1) atoms. Mn(1) is bonded to six equivalent Y(1), two equivalent Mn(1), and four equivalent Al(1) atoms to form MnY6Mn2Al4 cuboctahedra that share corners with eight equivalent Al(1)Y6Mn4Al2 cuboctahedra, corners with ten equivalent Mn(1)Y6Mn2Al4 cuboctahedra, edges with six equivalent Mn(1)Y6Mn2Al4 cuboctahedra, faces with six equivalent Mn(1)Y6Mn2Al4 cuboctahedra, and faces with twelve equivalent Al(1)Y6Mn4Al2 cuboctahedra. Al(1) is bonded to six equivalent Y(1), four equivalent Mn(1), and two equivalent Al(1) atoms to form AlY6Mn4Al2 cuboctahedra that share corners with eight equivalent Mn(1)Y6Mn2Al4 cuboctahedra, corners with ten equivalent Al(1)Y6Mn4Al2 cuboctahedra, edges with six equivalent Al(1)Y6Mn4Al2 cuboctahedra, faces with six equivalent Al(1)Y6Mn4Al2 cuboctahedra, and faces with twelve equivalent Mn(1)Y6Mn2Al4 cuboctahedra.
YMnAl is Hexagonal Laves-derived structured and crystallizes in the orthorhombic Imma space group. Y(1) is bonded in a 16-coordinate geometry to four equivalent Y(1), six equivalent Mn(1), and six equivalent Al(1) atoms. There are two shorter (3.33 Å) and two longer (3.38 Å) Y(1)-Y(1) bond lengths. There are two shorter (3.15 Å) and four longer (3.25 Å) Y(1)-Mn(1) bond lengths. All Y(1)-Al(1) bond lengths are 3.21 Å. Mn(1) is bonded to six equivalent Y(1), two equivalent Mn(1), and four equivalent Al(1) atoms to form MnY6Mn2Al4 cuboctahedra that share corners with eight equivalent Al(1)Y6Mn4Al2 cuboctahedra, corners with ten equivalent Mn(1)Y6Mn2Al4 cuboctahedra, edges with six equivalent Mn(1)Y6Mn2Al4 cuboctahedra, faces with six equivalent Mn(1)Y6Mn2Al4 cuboctahedra, and faces with twelve equivalent Al(1)Y6Mn4Al2 cuboctahedra. Both Mn(1)-Mn(1) bond lengths are 2.75 Å. All Mn(1)-Al(1) bond lengths are 2.73 Å.
