Title: Materials Data on NaNd9(Si3O13)2 by Materials Project

Abstract

NaNd9(Si3O13)2 crystallizes in the trigonal P3 space group. The structure is three-dimensional. Na1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Na–O bond distances ranging from 2.51–3.02 Å. There are five inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Nd–O bond distances ranging from 2.43–2.78 Å. In the second Nd3+ site, Nd3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Nd–O bond distances ranging from 2.43–2.81 Å. In the third Nd3+ site, Nd3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Nd–O bond distances ranging from 2.45–2.85 Å. In the fourth Nd3+ site, Nd3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Nd–O bond distances ranging from 2.29–2.81 Å. In the fifth Nd3+ site, Nd3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Nd–O bond distances ranging from 2.31–2.66 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded in a tetrahedral geometry tomore » four O2- atoms. There are a spread of Si–O bond distances ranging from 1.63–1.66 Å. In the second Si4+ site, Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.61 Å) and three longer (1.66 Å) Si–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Nd3+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Nd3+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, two Nd3+, and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to three Nd3+ and one Si4+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, two Nd3+, and one Si4+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to three Nd3+ and one Si4+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to three Nd3+ and one Si4+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to three Nd3+ and one Si4+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to three Nd3+ and one Si4+ atom. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, two Nd3+, and one Si4+ atom.« less
