Materials Data on NdSn2 by Materials Project
NdSn2 is Zirconium Disilicide-like structured and crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Nd is bonded in a 10-coordinate geometry to ten Sn atoms. There are a spread of Nd–Sn bond distances ranging from 3.26–3.59 Å. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a distorted square co-planar geometry to four equivalent Nd and four equivalent Sn atoms. All Sn–Sn bond lengths are 3.23 Å. In the second Sn site, Sn is bonded in a distorted square co-planar geometry to four equivalent Nd and four equivalent Sn atoms. In the third Sn site, Sn is bonded in a 4-coordinate geometry to six equivalent Nd and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.09 Å.
