Title: Materials Data on TlCu7Se4 by Materials Project

Abstract

TlCu7Se4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are seven inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded in a 3-coordinate geometry to three Se2- atoms. There are a spread of Cu–Se bond distances ranging from 2.43–2.65 Å. In the second Cu1+ site, Cu1+ is bonded to four Se2- atoms to form distorted corner-sharing CuSe4 tetrahedra. There are a spread of Cu–Se bond distances ranging from 2.40–2.76 Å. In the third Cu1+ site, Cu1+ is bonded in a distorted trigonal non-coplanar geometry to three Se2- atoms. There are a spread of Cu–Se bond distances ranging from 2.44–2.63 Å. In the fourth Cu1+ site, Cu1+ is bonded in a distorted trigonal non-coplanar geometry to three Se2- atoms. There are a spread of Cu–Se bond distances ranging from 2.38–2.59 Å. In the fifth Cu1+ site, Cu1+ is bonded in a 2-coordinate geometry to four Se2- atoms. There are a spread of Cu–Se bond distances ranging from 2.46–2.77 Å. In the sixth Cu1+ site, Cu1+ is bonded in a 4-coordinate geometry to four Se2- atoms. There are a spread of Cu–Se bond distances ranging from 2.41–2.71 Å. In the seventh Cu1+ site, Cu1+ is bondedmore » in a trigonal non-coplanar geometry to three Se2- atoms. There are one shorter (2.45 Å) and two longer (2.49 Å) Cu–Se bond lengths. Tl1+ is bonded in a body-centered cubic geometry to eight Se2- atoms. There are a spread of Tl–Se bond distances ranging from 3.30–3.54 Å. There are four inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 8-coordinate geometry to six Cu1+ and two equivalent Tl1+ atoms. In the second Se2- site, Se2- is bonded in a 8-coordinate geometry to six Cu1+ and two equivalent Tl1+ atoms. In the third Se2- site, Se2- is bonded in a 7-coordinate geometry to five Cu1+ and two equivalent Tl1+ atoms. In the fourth Se2- site, Se2- is bonded in a 9-coordinate geometry to seven Cu1+ and two equivalent Tl1+ atoms.« less
