Materials Data on KNa2P3H7N3O8 by Materials Project
Abstract
KNa2P3N3H7O8 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. K1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of K–O bond distances ranging from 2.73–2.89 Å. There are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with three PN2O2 tetrahedra and edges with three NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.33–2.53 Å. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with six PN2O2 tetrahedra and edges with three NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.41–2.82 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to two N3- and two O2- atoms to form PN2O2 tetrahedra that share corners with three NaO6 octahedra and corners with two PN2O2 tetrahedra. The corner-sharing octahedra tilt angles range from 54–61°. There is one shorter (1.69 Å) and one longer (1.70 Å) P–N bond length. There is one shorter (1.51 Å) and one longer (1.53 Å) P–O bond length. Inmore »
