Materials Data on TlV5S8 by Materials Project
TlV5S8 is Orthorhombic Perovskite-like structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are three inequivalent V3+ sites. In the first V3+ site, V3+ is bonded to six S2- atoms to form VS6 octahedra that share corners with three equivalent TlS10 cuboctahedra, corners with four equivalent VS6 octahedra, an edgeedge with one TlS10 cuboctahedra, edges with six VS6 octahedra, and a faceface with one VS6 octahedra. The corner-sharing octahedra tilt angles range from 49–54°. There are a spread of V–S bond distances ranging from 2.27–2.63 Å. In the second V3+ site, V3+ is bonded to six S2- atoms to form VS6 octahedra that share corners with four equivalent VS6 octahedra, edges with four equivalent TlS10 cuboctahedra, and edges with six VS6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are four shorter (2.39 Å) and two longer (2.40 Å) V–S bond lengths. In the third V3+ site, V3+ is bonded to six S2- atoms to form VS6 octahedra that share corners with four equivalent TlS10 cuboctahedra, corners with six VS6 octahedra, edges with four equivalent VS6 octahedra, a faceface with one TlS10 cuboctahedra, and a faceface with one VS6 octahedra. The corner-sharing octahedra tilt angles range from 47–54°. There are a spread of V–S bond distances ranging from 2.27–2.51 Å. Tl1+ is bonded to ten S2- atoms to form distorted TlS10 cuboctahedra that share corners with fourteen VS6 octahedra, edges with six VS6 octahedra, faces with two equivalent TlS10 cuboctahedra, and faces with two equivalent VS6 octahedra. The corner-sharing octahedra tilt angles range from 11–43°. There are a spread of Tl–S bond distances ranging from 3.17–3.32 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometry to four V3+ and one Tl1+ atom. In the second S2- site, S2- is bonded in a 3-coordinate geometry to three V3+ and two equivalent Tl1+ atoms. In the third S2- site, S2- is bonded in a 5-coordinate geometry to five V3+ atoms. In the fourth S2- site, S2- is bonded in a 3-coordinate geometry to three equivalent V3+ and two equivalent Tl1+ atoms.
