Title: Materials Data on Gd(PO3)3 by Materials Project

Abstract

Gd(PO3)3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded to six O2- atoms to form GdO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Gd–O bond distances ranging from 2.27–2.35 Å. In the second Gd3+ site, Gd3+ is bonded to six O2- atoms to form GdO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Gd–O bond distances ranging from 2.27–2.35 Å. There are seven 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 GdO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 28–42°. 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 two GdO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 11–32°. There is two shorter (1.50 Å) and two longer (1.61 Å) P–O bond length. In the third P5+ site,more » P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two GdO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 32–43°. There are a spread of P–O bond distances ranging from 1.50–1.61 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent GdO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 8–19°. There are a spread of P–O bond distances ranging from 1.50–1.61 Å. In the fifth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent GdO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 17°. There is two shorter (1.50 Å) and two longer (1.61 Å) P–O bond length. In the sixth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two GdO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 20–29°. There are a spread of P–O bond distances ranging from 1.50–1.61 Å. In the seventh P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent GdO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 25°. There is two shorter (1.50 Å) and two longer (1.60 Å) P–O bond length. There are eighteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Gd3+ 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 bent 150 degrees geometry to one Gd3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a linear geometry to one Gd3+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a linear geometry to one Gd3+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Gd3+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms. In the thirteenth O2- site, O2- is bonded in a distorted linear geometry to one Gd3+ and one P5+ atom. In the fourteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one P5+ atom. In the fifteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one P5+ atom. In the sixteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one P5+ atom. In the seventeenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Gd3+ and one P5+ atom. In the eighteenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Gd3+ and one P5+ atom.« less
