Title: Materials Data on NaNb4Tl3P2O17 by Materials Project

Abstract

NaNb4Tl3P2O17 crystallizes in the orthorhombic Ama2 space group. The structure is three-dimensional. Na1+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.46–2.53 Å. There are three inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with five NbO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 26–44°. There are a spread of Nb–O bond distances ranging from 1.89–2.23 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with four equivalent NbO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 26–37°. There are a spread of Nb–O bond distances ranging from 1.94–2.06 Å. In the third Nb5+ site, Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with four NbO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 28–39°. There are a spread of Nb–O bond distances ranging from 1.91–2.19 Å. There are three inequivalent Tl1+ sites. Inmore » the first Tl1+ site, Tl1+ is bonded in a 6-coordinate geometry to eight O2- atoms. There are a spread of Tl–O bond distances ranging from 2.82–3.44 Å. In the second Tl1+ site, Tl1+ is bonded in a 2-coordinate geometry to three O2- atoms. There are a spread of Tl–O bond distances ranging from 2.72–2.97 Å. In the third Tl1+ site, Tl1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Tl–O bond distances ranging from 2.74–3.27 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three NbO6 octahedra. The corner-sharing octahedra tilt angles range from 50–53°. There are a spread of P–O bond distances ranging from 1.53–1.59 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three NbO6 octahedra. The corner-sharing octahedra tilt angles range from 25–41°. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Nb5+ and two Tl1+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, two Tl1+, and one P5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, one Nb5+, one Tl1+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Nb5+ and one Tl1+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to two Nb5+ atoms. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Nb5+ and one Tl1+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one Nb5+, two equivalent Tl1+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Nb5+ and one Tl1+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to two Nb5+ and one Tl1+ atom. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, two Tl1+, and one P5+ atom. In the eleventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Nb5+, one Tl1+, and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Nb5+, one Tl1+, and one P5+ atom.« less
