Materials Data on EuYAl4 by Materials Project
EuYAl4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Eu is bonded in a 12-coordinate geometry to four equivalent Y and twelve equivalent Al atoms. All Eu–Y bond lengths are 3.45 Å. All Eu–Al bond lengths are 3.30 Å. Y is bonded in a 12-coordinate geometry to four equivalent Eu and twelve equivalent Al atoms. All Y–Al bond lengths are 3.30 Å. Al is bonded to three equivalent Eu, three equivalent Y, and six equivalent Al 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–Al bond lengths.
