Title: Materials Data on NdTa3O9 by Materials Project

Abstract

NdTa3O9 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded to twelve O2- atoms to form NdO12 cuboctahedra that share corners with three NdO12 cuboctahedra, faces with two equivalent NdO12 cuboctahedra, and faces with eight TaO6 octahedra. There are a spread of Nd–O bond distances ranging from 2.62–2.90 Å. In the second Nd3+ site, Nd3+ is bonded to twelve O2- atoms to form NdO12 cuboctahedra that share corners with three NdO12 cuboctahedra, faces with two equivalent NdO12 cuboctahedra, and faces with eight TaO6 octahedra. There are a spread of Nd–O bond distances ranging from 2.59–2.84 Å. There are six inequivalent Ta5+ sites.
