Materials Data on YErNi2 by Materials Project
ErYNi2 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. Er is bonded in a 7-coordinate geometry to seven Ni atoms. There are a spread of Er–Ni bond distances ranging from 2.85–2.96 Å. Y is bonded in a 7-coordinate geometry to seven Ni atoms. There are a spread of Y–Ni bond distances ranging from 2.86–2.94 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 9-coordinate geometry to three equivalent Er, four equivalent Y, and two equivalent Ni atoms. Both Ni–Ni bond lengths are 2.50 Å. In the second Ni site, Ni is bonded in a 9-coordinate geometry to four equivalent Er, three equivalent Y, and two equivalent Ni atoms.
