Materials Data on Ba2Nb15O32 by Materials Project

Kristin Persson
Ba2Nb15O32 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six NbO6 octahedra, edges with three equivalent BaO12 cuboctahedra, edges with three equivalent NbO6 octahedra, edges with three equivalent NbO5 square pyramids, and faces with three equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 44–54°. There are a spread of Ba–O bond distances ranging from 2.98–3.18...
