Materials Data on LuNiSn4 by Materials Project

Abstract

LuNiSn4 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Lu is bonded in a 10-coordinate geometry to ten Sn atoms. There are a spread of Lu–Sn bond distances ranging from 3.19–3.43 Å. Ni is bonded in a distorted body-centered cubic geometry to eight Sn atoms. There are a spread of Ni–Sn bond distances ranging from 2.67–2.76 Å. There are five inequivalent Sn sites. In the first Sn site, Sn is bonded in a 4-coordinate geometry to four equivalent Ni atoms. In the second Sn site, Sn is bonded in a 4-coordinate geometry to four equivalent Ni atoms. In the third Sn site, Sn is bonded in a 8-coordinate geometry to six equivalent Lu and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.03 Å. In the fourth Sn site, Sn is bonded in a 4-coordinate geometry to two equivalent Lu and two equivalent Ni atoms. In the fifth Sn site, Sn is bonded in a 4-coordinate geometry to two equivalent Lu and two equivalent Ni atoms.
