Materials Data on TaSn2 by Materials Project
TaSn2 is Khatyrkite-like structured and crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Ta is bonded in a 10-coordinate geometry to two equivalent Ta and eight Sn atoms. Both Ta–Ta bond lengths are 2.86 Å. There are a spread of Ta–Sn bond distances ranging from 2.89–2.99 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 4-coordinate geometry to four equivalent Ta atoms. In the second Sn site, Sn is bonded in a 4-coordinate geometry to four equivalent Ta atoms.
