Title: Materials Data on Ca3Tl4O9 by Materials Project

Abstract

Ca3Tl4O9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.30–2.75 Å. In the second Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.31–2.87 Å. In the third Ca2+ site, Ca2+ is bonded to six O2- atoms to form CaO6 octahedra that share corners with three TlO6 octahedra, an edgeedge with one CaO6 octahedra, and edges with six TlO6 octahedra. The corner-sharing octahedra tilt angles range from 7–63°. There are a spread of Ca–O bond distances ranging from 2.25–2.45 Å. There are four inequivalent Tl3+ sites. In the first Tl3+ site, Tl3+ is bonded to six O2- atoms to form TlO6 octahedra that share a cornercorner with one CaO6 octahedra, corners with two equivalent TlO6 octahedra, and edges with five TlO6 octahedra. The corner-sharing octahedra tilt angles range from 1–63°. There are a spread of Tl–O bond distances ranging from 2.14–2.44 Å. In the second Tl3+ site, Tl3+ is bonded tomore » six O2- atoms to form a mixture of corner and edge-sharing TlO6 octahedra. The corner-sharing octahedra tilt angles range from 1–62°.
