description: Ti3Cr3(SbO8)2 is beta Vanadium nitride-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent SbO6 octahedra, an edgeedge with one SbO6 octahedra, edges with two equivalent TiO6 octahedra, and edges with two equivalent CrO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of Ti–O bond distances ranging from 1.93–2.03 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent SbO6 octahedra, an edgeedge with one SbO6 octahedra, edges with two equivalent TiO6 octahedra, and edges with two equivalent CrO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Ti–O bond distances ranging from 1.93–2.04 Å. In the third Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent SbO6 octahedra, an edgeedge with one SbO6 octahedra, and edges with four CrO6 octahedra. The corner-sharing octahedra tilt angles range from 50–51°. There are a spread of Ti–O bond distances ranging from 1.93–2.13 Å. There are three inequivalent Cr4+ sites.

In the second Sb4+ site, Sb4+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent CrO6 octahedra, corners with four TiO6 octahedra, an edgeedge with one TiO6 octahedra, and edges with two CrO6 octahedra. The corner-sharing octahedra tilt angles range from 49–52°. There are a spread of Sb–O bond distances ranging from 1.99–2.07 Å. There are sixteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ti4+, one Cr4+, and one Sb4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Ti4+ and one Sb4+ atom.
