Materials Data on Ba3Nb6(Si2O13)2 by Materials Project

Kristin Persson
Ba3Nb6Si4O26 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Ba2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Ba–O bond distances ranging from 2.92–3.19 Å. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with four equivalent NbO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 4–31°. There are a spread of Nb–O...
