Materials Data on Ca3V2(Si2O7)2 by Materials Project

Computed materials data using density functional theory calculations. These calculations determine the electronic structure of bulk materials by solving approximations to the Schrodinger equation. For more information, see https://materialsproject.org/docs/calculations

Materials Data on CaVSiO5 by Materials Project

CaVSiO5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.34–2.63 Å. V4+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent VO6 octahedra and corners with four equivalent SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 37°. There are a spread of V–O bond distances ranging from 1.85–2.02 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four equivalent VO6 octahedra. The corner-sharing octahedra tilt angles range from 38–54°. All Si–O bond lengths are 1.65 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Ca2+ and two equivalent V4+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Ca2+, one V4+, and one Si4+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ca2+, one V4+, and one Si4+ atom.
