title: Materials Data on Ti(Sn2O5)2 by Materials Project

description: Ti(Sn2O5)2 is Hydrophilite-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with eight SnO6 octahedra and edges with two SnO6 octahedra. The corner-sharing octahedra tilt angles range from 47–50°. There are a spread of Ti–O bond distances ranging from 1.98–2.03 Å. There are five inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with four equivalent TiO6 octahedra, corners with four SnO6 octahedra, and edges with two SnO6 octahedra. The corner-sharing octahedra tilt angles range from 47–55°. There are a spread of Sn–O bond distances ranging from 2.07–2.11 Å. In the second Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with four equivalent TiO6 octahedra, corners with four equivalent SnO6 octahedra, and edges with two equivalent SnO6 octahedra. The corner-sharing octahedra tilt angles range from 48–54°. There are a spread of Sn–O bond distances ranging from 2.08–2.10 Å. In the third Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with six equivalent SnO6 octahedra, and edges with two SnO6 octahedra. The corner-sharing octahedra tilt angles range from 48–54°. There are a spread of Sn–O bond distances ranging from 2.07–2.10 Å. In the fourth Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with eight SnO6 octahedra, an edgeedge with one TiO6 octahedra, and an edgeedge with one SnO6 octahedra. The corner-sharing octahedra tilt angles range from 49–55°. There are a spread of Sn–O bond distances ranging from 2.07–2.11 Å. In the fifth Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with eight SnO6 octahedra and edges with two equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 50–55°. There are two shorter (2.06 Å) and four longer (2.11 Å) Sn–O bond lengths. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ti4+ and two Sn4+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ti4+ and two Sn4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ti4+ and two Sn4+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ti4+ and two Sn4+ atoms. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to three Sn4+ atoms. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ti4+ and two Sn4+ atoms. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ti4+ and two Sn4+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Sn4+ atoms. In the ninth O2- site, O2- is bonded in a trigonal planar geometry to three Sn4+ atoms. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Sn4+ atoms.
