Materials Data on NaPH7O6 by Materials Project
NaPH7O6 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of four NaPH7O6 ribbons oriented in the (0, 1, 0) direction. Na1+ is bonded to six O2- atoms to form edge-sharing NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.35–2.51 Å. P4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.53 Å) and one longer (1.60 Å) P–O bond length. There are seven inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.56 Å) H–O bond length. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.72 Å) H–O bond length. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one P4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one P4+, and one H1+ atom. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three H1+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one P4+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Na1+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Na1+ and two H1+ atoms.
