Materials Data on Na3Mo9P(H5O17)2 by Materials Project
(Na3Mo9PH3O34)2(H2)7 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional and consists of six hydrogen molecules, two H2 clusters, and one Na3Mo9PH3O34 framework. In each H2 cluster, there are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one H1+ atom. The H–H bond length is 1.07 Å. In the second H1+ site, H1+ is bonded in a trigonal planar geometry to three equivalent H1+ atoms. In the Na3Mo9PH3O34 framework, Na1+ is bonded in a 5-coordinate geometry to one H1+ and four O2- atoms. The Na–H bond length is 2.56 Å. There are a spread of Na–O bond distances ranging from 2.32–2.92 Å. There are three inequivalent Mo+5.56+ sites. In the first Mo+5.56+ site, Mo+5.56+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.73–2.46 Å. In the second Mo+5.56+ site, Mo+5.56+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.72–2.48 Å. In the third Mo+5.56+ site, Mo+5.56+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.73–2.48 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is three shorter (1.55 Å) and one longer (1.57 Å) P–O bond length. H1+ is bonded in a single-bond geometry to one Na1+ atom. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Na1+ and one Mo+5.56+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Na1+ and one Mo+5.56+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Mo+5.56+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two Mo+5.56+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two Mo+5.56+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Na1+ and one Mo+5.56+ atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to three equivalent Mo+5.56+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one Na1+ and one Mo+5.56+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one Mo+5.56+ atom. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to two Mo+5.56+ atoms. In the eleventh O2- site, O2- is bonded in a bent 150 degrees geometry to two Mo+5.56+ atoms. In the twelfth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Mo+5.56+ atoms.
