Materials Data on TlAgCl3 by Materials Project
AgTlCl3 is (Cubic) Perovskite structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. Ag2+ is bonded to six Cl1- atoms to form AgCl6 octahedra that share corners with six equivalent AgCl6 octahedra and faces with eight equivalent TlCl12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–2°. There are five shorter (2.56 Å) and one longer (2.57 Å) Ag–Cl bond lengths. Tl1+ is bonded to twelve Cl1- atoms to form TlCl12 cuboctahedra that share corners with twelve equivalent TlCl12 cuboctahedra, faces with six equivalent TlCl12 cuboctahedra, and faces with eight equivalent AgCl6 octahedra. There are a spread of Tl–Cl bond distances ranging from 3.56–3.69 Å. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted linear geometry to two equivalent Ag2+ and four equivalent Tl1+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted linear geometry to two equivalent Ag2+ and four equivalent Tl1+ atoms. In the third Cl1- site, Cl1- is bonded in a distorted linear geometry to two equivalent Ag2+ and four equivalent Tl1+ atoms.
