Materials Data on La5Sn3 by Materials Project

Abstract

La5Sn3 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 4-coordinate geometry to four equivalent Sn atoms. All La–Sn bond lengths are 3.31 Å. In the second La site, La is bonded in a 6-coordinate geometry to six Sn atoms. There are a spread of La–Sn bond distances ranging from 3.35–3.68 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 10-coordinate geometry to eight equivalent La and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.18 Å. In the second Sn site, Sn is bonded in a 10-coordinate geometry to ten La atoms.
