Materials Data on V5(P3O11)2 by Materials Project
V5(P3O11)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent V+2.80+ sites. In the first V+2.80+ site, V+2.80+ is bonded to six O2- atoms to form VO6 octahedra that share corners with four equivalent VO6 octahedra and corners with six PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 60–63°. There are four shorter (2.03 Å) and two longer (2.05 Å) V–O bond lengths. In the second V+2.80+ site, V+2.80+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent VO6 octahedra, corners with four PO4 tetrahedra, an edgeedge with one PO4 tetrahedra, and a faceface with one VO6 octahedra. The corner-sharing octahedra tilt angles range from 60–63°. There are a spread of V–O bond distances ranging from 2.03–2.22 Å. In the third V+2.80+ site, V+2.80+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one VO6 octahedra. There are a spread of V–O bond distances ranging from 1.94–2.29 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 five VO6 octahedra and an edgeedge with one VO6 octahedra. The corner-sharing octahedra tilt angles range from 39–53°. There are a spread of P–O bond distances ranging from 1.51–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with five VO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 37–61°. There are a spread of P–O bond distances ranging from 1.51–1.59 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent VO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 30–45°. There are a spread of P–O bond distances ranging from 1.52–1.64 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two V+2.80+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V+2.80+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one V+2.80+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one V+2.80+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two V+2.80+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two V+2.80+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V+2.80+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to two V+2.80+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V+2.80+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a 3-coordinate geometry to two V+2.80+ and one P5+ atom.
