Materials Data on Ba6Na2Nb2P2O17 by Materials Project

Kristin Persson
Ba6Na2Nb2P2O17 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with three equivalent NbO6 octahedra, corners with three equivalent PO4 tetrahedra, and faces with four BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 3°. There are three shorter (2.26 Å) and three longer (2.48 Å) Na–O bond lengths. There are four inequivalent Ba2+ sites. In the first Ba2+ site,...
