Materials Data on Dy2MgNi2 by Materials Project

MgDy2Ni2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Mg is bonded in a distorted square co-planar geometry to four equivalent Ni atoms. All Mg–Ni bond lengths are 2.92 Å. Dy is bonded in a 6-coordinate geometry to six equivalent Ni atoms. There are two shorter (2.84 Å) and four longer (2.88 Å) Dy–Ni bond lengths. Ni is bonded in a 9-coordinate geometry to two equivalent Mg, six equivalent Dy, and one Ni atom. The Ni–Ni bond length is 2.44 Å.

Materials Data on Dy4MgNi by Materials Project

Dy4NiMg crystallizes in the cubic F-43m space group. The structure is three-dimensional. Mg is bonded to three equivalent Mg and nine Dy atoms to form a mixture of face and corner-sharing MgDy9Mg3 cuboctahedra. All Mg–Mg bond lengths are 3.09 Å. There are a spread of Mg–Dy bond distances ranging from 3.28–3.53 Å. There are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a 3-coordinate geometry to three equivalent Mg, three equivalent Dy, and three equivalent Ni atoms. All Dy–Dy bond lengths are 3.51 Å. All Dy–Ni bond lengths are 2.79 Å. In the second Dy site, Dy is bonded in a bent 150 degrees geometry to two equivalent Mg, four equivalent Dy, and two equivalent Ni atoms. All Dy–Dy bond lengths are 3.62 Å. Both Dy–Ni bond lengths are 2.80 Å. In the third Dy site, Dy is bonded in a 4-coordinate geometry to two equivalent Mg, ten Dy, and two equivalent Ni atoms. All Dy–Dy bond lengths are 3.56 Å. Both Dy–Ni bond lengths are 3.51 Å. Ni is bonded in a 6-coordinate geometry to nine Dy atoms.
