Title: Materials Data on La11Sn10 by Materials Project

Abstract

La11Sn10 is delta Molybdenum Boride-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are four inequivalent La sites. In the first La site, La is bonded in a 8-coordinate geometry to eight Sn atoms. There are four shorter (3.63 Å) and four longer (3.64 Å) La–Sn bond lengths. In the second La site, La is bonded to seven Sn atoms to form a mixture of distorted face and edge-sharing LaSn7 pentagonal bipyramids. There are a spread of La–Sn bond distances ranging from 3.15–3.83 Å. In the third La site, La is bonded in a 7-coordinate geometry to seven Sn atoms. There are a spread of La–Sn bond distances ranging from 3.23–3.76 Å. In the fourth La site, La is bonded in a 7-coordinate geometry to seven Sn atoms. There are a spread of La–Sn bond distances ranging from 3.24–3.47 Å. There are five inequivalent Sn sites. In the first Sn site, Sn is bonded in a 8-coordinate geometry to eight La atoms. In the second Sn site, Sn is bonded in a 8-coordinate geometry to eight La atoms. In the third Sn site, Sn is bonded in a 9-coordinate geometry to seven La andmore » two equivalent Sn atoms. Both Sn–Sn bond lengths are 2.99 Å. In the fourth Sn site, Sn is bonded in a 6-coordinate geometry to eight La and one Sn atom. The Sn–Sn bond length is 3.31 Å. In the fifth Sn site, Sn is bonded in a 9-coordinate geometry to eight La and one Sn atom. The Sn–Sn bond length is 2.93 Å.« less
