Materials Data on GdSn2 by Materials Project
GdSn2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Gd is bonded in a 10-coordinate geometry to ten Sn atoms. There are a spread of Gd–Sn bond distances ranging from 3.19–3.48 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 8-coordinate geometry to four equivalent Gd and four equivalent Sn atoms. All Sn–Sn bond lengths are 3.14 Å. In the second Sn site, Sn is bonded in a 4-coordinate geometry to six equivalent Gd and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.04 Å.
