Title: Materials Data on NaLaCuTe4 by Materials Project

Abstract

NaLaCuTe4 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Na1+ is bonded in a 8-coordinate geometry to eight Te+1.50- atoms. There are four shorter (3.28 Å) and four longer (3.56 Å) Na–Te bond lengths. La3+ is bonded in a 9-coordinate geometry to nine Te+1.50- atoms. There are a spread of La–Te bond distances ranging from 3.28–3.40 Å. Cu2+ is bonded to four equivalent Te+1.50- atoms to form a mixture of corner and edge-sharing CuTe4 tetrahedra. All Cu–Te bond lengths are 2.72 Å. There are three inequivalent Te+1.50- sites. In the first Te+1.50- site, Te+1.50- is bonded in a 8-coordinate geometry to two equivalent Na1+, two equivalent La3+, and four equivalent Te+1.50- atoms. All Te–Te bond lengths are 3.15 Å. In the second Te+1.50- site, Te+1.50- is bonded in a 8-coordinate geometry to four equivalent Na1+ and four equivalent Cu2+ atoms. In the third Te+1.50- site, Te+1.50- is bonded in a 5-coordinate geometry to five equivalent La3+ atoms.
