Title: Materials Data on Na3NbAs2O9 by Materials Project

Abstract

Na3NbO(AsO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.31–2.93 Å. In the second Na1+ site, Na1+ is bonded in a distorted pentagonal planar geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.34–2.50 Å. In the third Na1+ site, Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.35–2.45 Å. Nb5+ is bonded in a distorted octahedral geometry to six O2- atoms. There are a spread of Nb–O bond distances ranging from 1.82–2.26 Å. There are two inequivalent As5+ sites. In the first As5+ site, As5+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of As–O bond distances ranging from 1.76–2.52 Å. In the second As5+ site, As5+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of As–O bond distances ranging from 1.81–1.85 Å. There are nine inequivalent O2- sites. In the firstmore » O2- site, O2- is bonded in a distorted see-saw-like geometry to two Na1+, one Nb5+, and one As5+ atom. In the second O2- site, O2- is bonded in a distorted T-shaped geometry to one Na1+, one Nb5+, and one As5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two Na1+ and one Nb5+ atom. In the fourth O2- site, O2- is bonded in a trigonal non-coplanar geometry to one Na1+ and two As5+ atoms. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two Na1+, one Nb5+, and one As5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to three Na1+ and one O2- atom. The O–O bond length is 1.38 Å. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Nb5+, and one O2- atom. The O–O bond length is 1.44 Å. In the eighth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Na1+, one Nb5+, and one As5+ atom. In the ninth O2- site, O2- is bonded in a 4-coordinate geometry to two Na1+, one As5+, and one O2- atom.« less
