Abstract

Na3(PO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Na sites. In the first Na site, Na is bonded to six O atoms to form distorted NaO6 octahedra that share a cornercorner with one NaO6 octahedra, corners with five PO4 tetrahedra, and edges with four NaO6 octahedra. The corner-sharing octahedral tilt angles are 45°. There are a spread of Na–O bond distances ranging from 2.36–2.68 Å. In the second Na site, Na is bonded to six O atoms to form distorted NaO6 octahedra that share corners with two equivalent NaO6 octahedra, corners with three PO4 tetrahedra, edges with five NaO6 octahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 48–71°. There are a spread of Na–O bond distances ranging from 2.35–2.75 Å. In the third Na site, Na is bonded to six O atoms to form distorted NaO6 octahedra that share corners with three NaO6 octahedra, corners with five PO4 tetrahedra, and edges with three NaO6 octahedra. The corner-sharing octahedra tilt angles range from 45–71°. There are a spread of Na–O bond distances ranging from 2.34–2.65 Å. There are two inequivalent P sites. In the first Pmore »« less
