Title: Materials Data on Na2PHO3 by Materials Project

Abstract

Na2PHO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 square pyramids that share corners with two equivalent NaO6 square pyramids, corners with four equivalent PHO3 tetrahedra, edges with two equivalent NaO6 square pyramids, and an edgeedge with one PHO3 tetrahedra. There are a spread of Na–O bond distances ranging from 2.40–2.95 Å. In the second Na1+ site, Na1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.35–2.72 Å. P5+ is bonded to one H1- and three O2- atoms to form distorted PHO3 tetrahedra that share corners with four equivalent NaO6 square pyramids and an edgeedge with one NaO6 square pyramid. The P–H bond length is 1.42 Å. There is one shorter (1.54 Å) and two longer (1.55 Å) P–O bond length. H1- is bonded in a distorted single-bond geometry to one P5+ atom. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to four Na1+ and one P5+ atom. In the second O2- site,more » O2- is bonded in a 1-coordinate geometry to four Na1+ and one P5+ atom. In the third O2- site, O2- is bonded to three Na1+ and one P5+ atom to form distorted corner-sharing ONa3P trigonal pyramids.« less
