Materials Data on Mo2P3O13 by Materials Project

Abstract

Mo2P3O13 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Mo+5.50+ sites. In the first Mo+5.50+ site, Mo+5.50+ is bonded to six O2- atoms to form distorted MoO6 octahedra that share corners with five PO4 tetrahedra. There are a spread of Mo–O bond distances ranging from 1.69–2.25 Å. In the second Mo+5.50+ site, Mo+5.50+ is bonded to six O2- atoms to form distorted MoO6 octahedra that share corners with five PO4 tetrahedra. There are a spread of Mo–O bond distances ranging from 1.69–2.23 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 three MoO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 38–51°. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four MoO6 octahedra. The corner-sharing octahedra tilt angles range from 34–46°. There are a spread of P–O bond distances ranging from 1.52–1.57 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three MoO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 41–46°. There are a spread of P–O bond distances ranging from 1.49–1.62 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo+5.50+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Mo+5.50+ and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Mo+5.50+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo+5.50+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Mo+5.50+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo+5.50+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one Mo+5.50+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Mo+5.50+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo+5.50+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a single-bond geometry to one Mo+5.50+ atom. In the eleventh O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the twelfth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo+5.50+ and one P5+ atom. In the thirteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo+5.50+ and one P5+ atom.
