Materials Data on DyMg3 by Materials Project

Mg3Dy is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded in a body-centered cubic geometry to four equivalent Mg and four equivalent Dy atoms. All Mg–Mg bond lengths are 3.17 Å. All Mg–Dy bond lengths are 3.17 Å. In the second Mg site, Mg is bonded in a 8-coordinate geometry to eight equivalent Mg and six equivalent Dy atoms. All Mg–Dy bond lengths are 3.66 Å. Dy is bonded in a distorted body-centered cubic geometry to fourteen Mg atoms.

Materials Data on DyMg2 by Materials Project

Mg2Dy is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded to six equivalent Mg and six equivalent Dy atoms to form a mixture of face, edge, and corner-sharing MgDy6Mg6 cuboctahedra. All Mg–Mg bond lengths are 3.03 Å. All Mg–Dy bond lengths are 3.55 Å. In the second Mg site, Mg is bonded to six Mg and six equivalent Dy atoms to form a mixture of face, edge, and corner-sharing MgDy6Mg6 cuboctahedra. There are two shorter (2.95 Å) and two longer (3.11 Å) Mg–Mg bond lengths. There are two shorter (3.51 Å) and four longer (3.53 Å) Mg–Dy bond lengths. Dy is bonded in a 12-coordinate geometry to twelve Mg and four equivalent Dy atoms. There are one shorter (3.64 Å) and three longer (3.71 Å) Dy–Dy bond lengths.
