Materials Data on SmDyNi2 by Materials Project
DySmNi2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Dy is bonded in a 7-coordinate geometry to seven Ni atoms. There are a spread of Dy–Ni bond distances ranging from 2.85–2.98 Å. Sm is bonded in a 7-coordinate geometry to seven Ni atoms. There are a spread of Sm–Ni bond distances ranging from 2.88–2.94 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 9-coordinate geometry to three equivalent Dy, four equivalent Sm, and two equivalent Ni atoms. Both Ni–Ni bond lengths are 2.57 Å. In the second Ni site, Ni is bonded in a 9-coordinate geometry to four equivalent Dy, three equivalent Sm, and two equivalent Ni atoms.
