Title: Materials Data on VPNO5 by Materials Project

Abstract

(VOPO4)2N2 crystallizes in the orthorhombic Pnn2 space group. The structure is three-dimensional and consists of eight ammonia molecules and one VOPO4 framework. In the VOPO4 framework, there are two inequivalent V4+ sites. In the first V4+ site, V4+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent VO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 41–43°. There are a spread of V–O bond distances ranging from 1.68–2.04 Å. In the second V4+ site, V4+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent VO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 41–43°. There are a spread of V–O bond distances ranging from 1.68–2.12 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 corners with four VO6 octahedra. The corner-sharing octahedra tilt angles range from 41–51°. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra thatmore » share corners with four VO6 octahedra. The corner-sharing octahedra tilt angles range from 37–51°. There is three shorter (1.55 Å) and one longer (1.56 Å) P–O bond length. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four VO6 octahedra. The corner-sharing octahedra tilt angles range from 40–49°. There is two shorter (1.54 Å) and two longer (1.57 Å) P–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one V4+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one V4+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one V4+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one V4+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one V4+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two V4+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V4+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two V4+ atoms. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V4+ and one P5+ atom.« less
