Abstract

TlV5Se8 is Orthorhombic Perovskite-like structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent V3+ sites. In the first V3+ site, V3+ is bonded to six Se2- atoms to form distorted VSe6 octahedra that share corners with three equivalent TlSe10 cuboctahedra, corners with four equivalent VSe6 octahedra, an edgeedge with one TlSe10 cuboctahedra, edges with six VSe6 octahedra, and a faceface with one VSe6 octahedra. The corner-sharing octahedra tilt angles range from 50–55°. There are a spread of V–Se bond distances ranging from 2.42–2.74 Å. In the second V3+ site, V3+ is bonded to six Se2- atoms to form VSe6 octahedra that share corners with four equivalent TlSe10 cuboctahedra, corners with six VSe6 octahedra, edges with four equivalent VSe6 octahedra, a faceface with one TlSe10 cuboctahedra, and a faceface with one VSe6 octahedra. The corner-sharing octahedra tilt angles range from 50–55°. There are a spread of V–Se bond distances ranging from 2.51–2.60 Å. In the third V3+ site, V3+ is bonded to six Se2- atoms to form VSe6 octahedra that share corners with four equivalent VSe6 octahedra, edges with four equivalent TlSe10 cuboctahedra, and edges with six VSe6 octahedra.
