Materials Data on TmSn2 by Materials Project
TmSn2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Tm is bonded in a 10-coordinate geometry to ten Sn atoms. There are a spread of Tm–Sn bond distances ranging from 3.14–3.43 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 4-coordinate geometry to six equivalent Tm and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.01 Å. In the second Sn site, Sn is bonded in a 8-coordinate geometry to four equivalent Tm and four equivalent Sn atoms. All Sn–Sn bond lengths are 3.09 Å.
