EuYAl4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Y(1) and twelve equivalent Al(1) atoms. Y(1) is bonded in a 16-coordinate geometry to four equivalent Eu(1) and twelve equivalent Al(1) atoms. Al(1) is bonded to three equivalent Eu(1), three equivalent Y(1), and six equivalent Al(1) atoms to form a mixture of edge, corner, and face-sharing AlEu3Y3Al6 cuboctahedra.
EuYAl4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Y(1) and twelve equivalent Al(1) atoms. All Eu(1)-Y(1) bond lengths are 3.45 Å. All Eu(1)-Al(1) bond lengths are 3.30 Å. Y(1) is bonded in a 16-coordinate geometry to four equivalent Eu(1) and twelve equivalent Al(1) atoms. All Y(1)-Al(1) bond lengths are 3.30 Å. Al(1) is bonded to three equivalent Eu(1), three equivalent Y(1), and six equivalent Al(1) atoms to form a mixture of edge, corner, and face-sharing AlEu3Y3Al6 cuboctahedra. There are three shorter (2.81 Å) and three longer (2.82 Å) Al(1)-Al(1) bond lengths.
