Materials Data on LuTe2 by Materials Project
LuTe2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Lu3+ is bonded in a 9-coordinate geometry to nine Te+1.50- atoms. There are a spread of Lu–Te bond distances ranging from 3.11–3.25 Å. There are two inequivalent Te+1.50- sites. In the first Te+1.50- site, Te+1.50- is bonded in a 8-coordinate geometry to four equivalent Lu3+ and four equivalent Te+1.50- atoms. All Te–Te bond lengths are 3.12 Å. In the second Te+1.50- site, Te+1.50- is bonded to five equivalent Lu3+ atoms to form a mixture of distorted edge and corner-sharing TeLu5 trigonal bipyramids.
