Materials Data on P3RuO9 by Materials Project

RuP3O9 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Ru3+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with six PO4 tetrahedra. There are four shorter (2.04 Å) and two longer (2.07 Å) Ru–O bond lengths. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent RuO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 38–44°. There are a spread of P–O bond distances ranging from 1.50–1.59 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent RuO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 36°. There is two shorter (1.50 Å) and two longer (1.59 Å) P–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ru3+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ru3+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ru3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a linear geometry to two equivalent P5+ atoms.

Materials Data on P3RuO9 by Materials Project

RuP3O9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Ru3+ sites. In the first Ru3+ site, Ru3+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Ru–O bond distances ranging from 2.05–2.09 Å. In the second Ru3+ site, Ru3+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with six PO4 tetrahedra. There are four shorter (2.05 Å) and two longer (2.09 Å) Ru–O bond lengths. 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 two equivalent RuO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 49–55°. There are a spread of P–O bond distances ranging from 1.50–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two RuO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 48–55°. There are a spread of P–O bond distances ranging from 1.51–1.61 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent RuO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Ru3+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ru3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ru3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ru3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Ru3+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ru3+ and one P5+ atom.
