Materials Data on RbScBP2HO9 by Materials Project

Abstract

RbScBP2HO9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.93–3.39 Å. Sc3+ is bonded to six O2- atoms to form ScO6 octahedra that share a cornercorner with one BO4 tetrahedra and corners with five PO4 tetrahedra. There are a spread of Sc–O bond distances ranging from 2.08–2.19 Å. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share a cornercorner with one ScO6 octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedral tilt angles are 46°. There are a spread of B–O bond distances ranging from 1.46–1.50 Å. 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 three equivalent ScO6 octahedra and a cornercorner with one BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 25–44°. There are a spread of P–O bond distances ranging from 1.52–1.58 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent ScO6 octahedra and corners with two equivalent BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 33–53°. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Sc3+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Rb1+, one Sc3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Sc3+, one B3+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Sc3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one B3+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Rb1+, one Sc3+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one B3+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Rb1+, one Sc3+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one B3+, and one P5+ atom.
