EuFe2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Eu(1), three equivalent Fe(1), and nine equivalent Fe(2) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to six equivalent Eu(1) and six equivalent Fe(2) atoms to form a mixture of edge, corner, and face-sharing FeEu6Fe6 cuboctahedra. In the second Fe site, Fe(2) is bonded to six equivalent Eu(1), two equivalent Fe(1), and four equivalent Fe(2) atoms to form a mixture of edge, corner, and face-sharing FeEu6Fe6 cuboctahedra.
EuFe2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Eu(1), three equivalent Fe(1), and nine equivalent Fe(2) atoms. There is one shorter (3.29 Å) and three longer (3.32 Å) Eu(1)-Eu(1) bond lengths. All Eu(1)-Fe(1) bond lengths are 3.21 Å. There are three shorter (3.17 Å) and six longer (3.21 Å) Eu(1)-Fe(2) bond lengths. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to six equivalent Eu(1) and six equivalent Fe(2) atoms to form a mixture of edge, corner, and face-sharing FeEu6Fe6 cuboctahedra. All Fe(1)-Fe(2) bond lengths are 2.55 Å. In the second Fe site, Fe(2) is bonded to six equivalent Eu(1), two equivalent Fe(1), and four equivalent Fe(2) atoms to form a mixture of edge, corner, and face-sharing FeEu6Fe6 cuboctahedra. There are two shorter (2.43 Å) and two longer (3.07 Å) Fe(2)-Fe(2) bond lengths.
