Abstract

Dy3TbAl8 is Hexagonal Laves-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a 12-coordinate geometry to four Dy and twelve Al atoms. There are three shorter (3.41 Å) and one longer (3.42 Å) Dy–Dy bond lengths. All Dy–Al bond lengths are 3.26 Å. In the second Dy site, Dy is bonded in a 12-coordinate geometry to three equivalent Dy, one Tb, and twelve Al atoms. The Dy–Tb bond length is 3.41 Å. All Dy–Al bond lengths are 3.26 Å. In the third Dy site, Dy is bonded in a 12-coordinate geometry to one Dy, three equivalent Tb, and twelve Al atoms. All Dy–Tb bond lengths are 3.41 Å. There are six shorter (3.26 Å) and six longer (3.27 Å) Dy–Al bond lengths. Tb is bonded in a 12-coordinate geometry to four Dy and twelve Al atoms. All Tb–Al bond lengths are 3.26 Å. There are four inequivalent Al sites. In the first Al site, Al is bonded to three equivalent Dy, three equivalent Tb, and six Al atoms to form AlTb3Dy3Al6 cuboctahedra that share corners with eighteen AlDy6Al6 cuboctahedra, edgesmore »« less
