Title: Materials Data on BaNbTePO8 by Materials Project

Abstract

BaNbPTeO8 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.77–3.32 Å. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with two equivalent NbO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 29°. There are a spread of Nb–O bond distances ranging from 1.84–2.13 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one NbO6 octahedra. The corner-sharing octahedral tilt angles are 38°. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.91–2.34 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ba2+, one Nb5+, and one Te4+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Nb5+ atoms. In the third O2- site, O2- is bonded in amore » 2-coordinate geometry to one Ba2+, one Nb5+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Nb5+ and one Te4+ atom. In the sixth O2- site, O2- is bonded in a linear geometry to one Nb5+ and one Te4+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one P5+, and one Te4+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one P5+ atom.« less
