title: Materials Data on NaV3P3O13 by Materials Project

description: NaV3P3O13 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.44–2.96 Å. There are three inequivalent V+3.33+ sites. In the first V+3.33+ site, V+3.33+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with two equivalent VO6 octahedra, a cornercorner with one VO5 square pyramid, corners with three PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of V–O bond distances ranging from 1.82–2.19 Å. In the second V+3.33+ site, V+3.33+ is bonded to five O2- atoms to form VO5 square pyramids that share a cornercorner with one VO6 octahedra and corners with five PO4 tetrahedra. The corner-sharing octahedral tilt angles are 55°. There are a spread of V–O bond distances ranging from 1.93–2.05 Å. In the third V+3.33+ site, V+3.33+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent VO6 octahedra, corners with four PO4 tetrahedra, and edges with two equivalent VO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of V–O bond distances ranging from 2.00–2.09 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one VO6 octahedra and corners with three equivalent VO5 square pyramids. The corner-sharing octahedral tilt angles are 33°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four VO6 octahedra and a cornercorner with one VO5 square pyramid. The corner-sharing octahedra tilt angles range from 40–54°. There are a spread of P–O bond distances ranging from 1.52–1.59 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent VO6 octahedra, a cornercorner with one VO5 square pyramid, and an edgeedge with one VO6 octahedra. The corner-sharing octahedral tilt angles are 48°. There is two shorter (1.54 Å) and two longer (1.56 Å) P–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent V+3.33+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two V+3.33+ and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one V+3.33+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one V+3.33+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one V+3.33+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one V+3.33+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to three V+3.33+ atoms. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one V+3.33+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one V+3.33+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one V+3.33+, and one P5+ atom.
