Materials Data on Er2NiSn6 by Materials Project
Er2NiSn6 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Er is bonded in a 10-coordinate geometry to ten Sn atoms. There are a spread of Er–Sn bond distances ranging from 3.16–3.44 Å. Ni is bonded in a body-centered cubic geometry to eight Sn atoms. All Ni–Sn bond lengths are 2.71 Å. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a 4-coordinate geometry to two equivalent Er and two equivalent Ni atoms. In the second Sn site, Sn is bonded in a 4-coordinate geometry to two equivalent Er and two equivalent Ni atoms. In the third Sn site, Sn is bonded in a 4-coordinate geometry to six equivalent Er and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.01 Å.
