Materials Data on Tl8Ge5O14 by Materials Project
Tl8Ge5O14 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are four inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Tl–O bond distances ranging from 2.56–3.36 Å. In the second Tl1+ site, Tl1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Tl–O bond distances ranging from 2.56–3.36 Å. In the third Tl1+ site, Tl1+ is bonded in a 3-coordinate geometry to three O2- atoms. All Tl–O bond lengths are 2.59 Å. In the fourth Tl1+ site, Tl1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Tl–O bond distances ranging from 2.56–3.37 Å. There are three inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There is two shorter (1.76 Å) and two longer (1.81 Å) Ge–O bond length. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There is one shorter (1.74 Å) and three longer (1.79 Å) Ge–O bond length. In the third Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There is two shorter (1.76 Å) and two longer (1.81 Å) Ge–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Tl1+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Tl1+ and two Ge4+ atoms. In the third O2- site, O2- is bonded in a distorted tetrahedral geometry to three Tl1+ and one Ge4+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Tl1+ and two Ge4+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Tl1+ and two Ge4+ atoms. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to three Tl1+ and one Ge4+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to three Tl1+ and one Ge4+ atom.
