Materials Data on Sc6Sn5 by Materials Project
Sc6Sn5 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. there are three inequivalent Sc sites. In the first Sc site, Sc is bonded in a 6-coordinate geometry to six Sn atoms. There are a spread of Sc–Sn bond distances ranging from 2.92–3.11 Å. In the second Sc site, Sc is bonded in a 7-coordinate geometry to seven Sn atoms. There are a spread of Sc–Sn bond distances ranging from 2.85–3.32 Å. In the third Sc site, Sc is bonded in a 7-coordinate geometry to seven Sn atoms. There are a spread of Sc–Sn bond distances ranging from 2.90–3.41 Å. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a 9-coordinate geometry to nine Sc atoms. In the second Sn site, Sn is bonded in a 10-coordinate geometry to eight Sc and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.06 Å. In the third Sn site, Sn is bonded in a 7-coordinate geometry to seven Sc atoms.
