Materials Data on NdTa7O19 by Materials Project

Kristin Persson
NdTa7O19 crystallizes in the hexagonal P-6c2 space group. The structure is three-dimensional. Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are six shorter (2.46 Å) and two longer (2.66 Å) Nd–O bond lengths. There are two inequivalent Ta5+ sites. In the first Ta5+ site, Ta5+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ta–O bond distances ranging from 1.93–2.49 Å. In the second Ta5+...
