Materials Data on Lu11Ge10 by Materials Project

Abstract

Lu11Ge10 is delta Molybdenum Boride-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are four inequivalent Lu sites. In the first Lu site, Lu is bonded to seven Ge atoms to form a mixture of distorted edge, face, and corner-sharing LuGe7 pentagonal bipyramids. There are a spread of Lu–Ge bond distances ranging from 2.82–3.25 Å. In the second Lu site, Lu is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Lu–Ge bond distances ranging from 2.72–3.36 Å. In the third Lu site, Lu is bonded in a 9-coordinate geometry to nine Ge atoms. There are a spread of Lu–Ge bond distances ranging from 3.16–3.58 Å. In the fourth Lu site, Lu is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Lu–Ge bond distances ranging from 2.84–3.02 Å. There are five inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to eight Lu atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to nine Lu atoms. In the third Ge site, Ge is bonded in a 9-coordinate geometry to seven Lu and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.60 Å. In the fourth Ge site, Ge is bonded in a 8-coordinate geometry to eight Lu atoms. In the fifth Ge site, Ge is bonded in a 9-coordinate geometry to eight Lu and one Ge atom. The Ge–Ge bond length is 2.55 Å.
