La Be Be Fe
Be2LaFe crystallizes in the trigonal R3m space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded to one Be(2), three equivalent La(1), and three equivalent Fe(1) atoms to form distorted edge-sharing BeLa3BeFe3 hexagonal pyramids. The Be(1)-Be(2) bond length is 2.32 Å. All Be(1)-La(1) bond lengths are 2.71 Å. All Be(1)-Fe(1) bond lengths are 2.71 Å. In the second Be site, Be(2) is bonded in a 1-coordinate geometry to one Be(1), three equivalent La(1), and one Fe(1) atom. All Be(2)-La(1) bond lengths are 2.71 Å. The Be(2)-Fe(1) bond length is 2.08 Å. La(1) is bonded in a 10-coordinate geometry to three equivalent Be(1), three equivalent Be(2), and four equivalent Fe(1) atoms. There is one shorter (2.32 Å) and three longer (2.96 Å) La(1)-Fe(1) bond lengths. Fe(1) is bonded in a distorted linear geometry to one Be(2), three equivalent Be(1), and four equivalent La(1) atoms.
