Materials Data on CsTlCl3 by Materials Project

CsTlCl3 is (Cubic) Perovskite structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. Cs is bonded to twelve Cl atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent CsCl12 cuboctahedra, faces with six equivalent CsCl12 cuboctahedra, and faces with eight equivalent TlCl6 octahedra. There are a spread of Cs–Cl bond distances ranging from 3.89–4.00 Å. Tl is bonded to six Cl atoms to form TlCl6 octahedra that share corners with six equivalent TlCl6 octahedra and faces with eight equivalent CsCl12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–2°. All Tl–Cl bond lengths are 2.79 Å. There are three inequivalent Cl sites. In the first Cl site, Cl is bonded to four equivalent Cs and two equivalent Tl atoms to form a mixture of distorted edge, face, and corner-sharing ClCs4Tl2 octahedra. The corner-sharing octahedra tilt angles range from 1–61°. In the second Cl site, Cl is bonded to four equivalent Cs and two equivalent Tl atoms to form a mixture of distorted edge, face, and corner-sharing ClCs4Tl2 octahedra. The corner-sharing octahedra tilt angles range from 1–61°. In the third Cl site, Cl is bonded to four equivalent Cs and two equivalent Tl atoms to form a mixture of distorted edge, face, and corner-sharing ClCs4Tl2 octahedra. The corner-sharing octahedra tilt angles range from 0–61°.
