description: Ti3(SnO5)2 is Hydrophilite-derived structured and crystallizes in the orthorhombic Cmm2 space group. The structure is three-dimensional. there are six inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four equivalent TiO6 octahedra, corners with four equivalent SnO6 octahedra, an edgeedge with one TiO6 octahedra, and an edgeedge with one SnO6 octahedra. The corner-sharing octahedra tilt angles range from 47–51°. There are a spread of Ti–O bond distances ranging from 1.93–2.02 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four equivalent TiO6 octahedra, corners with four equivalent SnO6 octahedra, and edges with two TiO6 octahedra. The corner-sharing octahedra tilt angles range from 45–52°. There are a spread of Ti–O bond distances ranging from 1.97–2.01 Å. In the third Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four equivalent TiO6 octahedra, corners with four equivalent SnO6 octahedra, an edgeedge with one TiO6 octahedra, and an edgeedge with one SnO6 octahedra. The corner-sharing octahedra tilt angles range from 45–52°. There are a spread of Ti–O bond distances ranging from 1.97–2.00 Å. In the fourth Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with eight SnO6 octahedra and edges with two TiO6 octahedra. The corner-sharing octahedra tilt angles range from 49–51°. There is four shorter (1.98 Å) and two longer (2.00 Å) Ti–O bond length.

In the sixth Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with eight TiO6 octahedra and edges with two SnO6 octahedra. The corner-sharing octahedra tilt angles range from 45–49°. There are a spread of Ti–O bond distances ranging from 1.94–2.05 Å. There are four 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 equivalent SnO6 octahedra, and edges with two TiO6 octahedra. The corner-sharing octahedra tilt angles range from 49–54°. There are a spread of Sn–O bond distances ranging from 2.07–2.10 Å. In the second Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with eight TiO6 octahedra, an edgeedge with one TiO6 octahedra, and an edgeedge with one SnO6 octahedra. The corner-sharing octahedra tilt angles range from 49–52°. There are four shorter (2.08 Å) and two longer (2.10 Å) Sn–O bond lengths. In the third 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 TiO6 octahedra. The corner-sharing octahedra tilt angles range from 50–54°. 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 TiO6 octahedra, an edgeedge with one TiO6 octahedra, and an edgeedge with one SnO6 octahedra. The corner-sharing octahedra tilt angles range from 49–52°. There are four shorter (2.08 Å) and two longer (2.10 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 two Ti4+ and one Sn4+ atom.
