Materials Data on Cs2Ti(Si2O5)3 by Materials Project
Abstract
Cs2TiSi6O15 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Cs1+ is bonded in a 6-coordinate geometry to ten O2- atoms. There are a spread of Cs–O bond distances ranging from 3.08–3.70 Å. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six SiO4 tetrahedra. There is two shorter (1.97 Å) and four longer (1.98 Å) Ti–O bond length. There are three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one TiO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 45°. There are a spread of Si–O bond distances ranging from 1.61–1.66 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one TiO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 46°. There are a spread of Si–O bond distances ranging from 1.61–1.66 Å. In the third Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one TiO6 octahedra and corners with three SiO4more »
