Materials Data on Er2P4O13 by Materials Project
Er2P4O13 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded to six O2- atoms to form ErO6 octahedra that share corners with six PO4 tetrahedra and an edgeedge with one ErO6 octahedra. There are a spread of Er–O bond distances ranging from 2.16–2.37 Å. In the second Er3+ site, Er3+ is bonded to six O2- atoms to form ErO6 octahedra that share corners with six PO4 tetrahedra and an edgeedge with one ErO6 octahedra. There are a spread of Er–O bond distances ranging from 2.16–2.37 Å. There are four inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four ErO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 13–56°. There are a spread of P–O bond distances ranging from 1.51–1.62 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two ErO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 26–43°. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two ErO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 21–33°. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four ErO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 7–55°. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to one Er3+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Er3+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Er3+ and one P5+ atom. 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 Er3+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Er3+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Er3+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the twelfth O2- site, O2- is bonded in a distorted linear geometry to one Er3+ and one P5+ atom. In the thirteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one P5+ atom.
