Materials Data on Li3TlPCO7 by Materials Project

Abstract

Li3TlCPO7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.90–2.06 Å. In the second Li1+ site, Li1+ is bonded in a 3-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.04–2.47 Å. In the third Li1+ site, Li1+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.95–2.22 Å. Tl3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Tl–O bond distances ranging from 2.45–2.88 Å. C3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.29–1.32 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.55 Å) and two longer (1.57 Å) P–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Li1+, one Tl3+, and one C3+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two Li1+, one Tl3+, and one C3+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Li1+, one Tl3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Tl3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, two equivalent Tl3+, and one C3+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Li1+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, one Tl3+, and one P5+ atom.
