Materials Data on LaNb7O19 by Materials Project

Kristin Persson
LaNb7O19 crystallizes in the trigonal P321 space group. The structure is three-dimensional. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.47–2.69 Å. There are four inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded in a distorted octahedral geometry to six O2- atoms. There are three shorter (1.96 Å) and three longer (2.09 Å) Nb–O bond lengths. In the second...
