Materials Data on SbP2O7 by Materials Project
SbP2O7 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are two inequivalent Sb5+ sites. In the first Sb5+ site, Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Sb–O bond distances ranging from 1.97–2.00 Å. In the second Sb5+ site, Sb5+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Sb–O bond distances ranging from 2.10–2.42 Å. There are four inequivalent P+4.50+ sites. In the first P+4.50+ site, P+4.50+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent SbO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 41–42°. There are a spread of P–O bond distances ranging from 1.49–1.61 Å. In the second P+4.50+ site, P+4.50+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one SbO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 39°. There are a spread of P–O bond distances ranging from 1.49–1.64 Å. In the third P+4.50+ site, P+4.50+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent SbO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 23–32°. There are a spread of P–O bond distances ranging from 1.50–1.58 Å. In the fourth P+4.50+ site, P+4.50+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one SbO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. There are a spread of P–O bond distances ranging from 1.51–1.61 Å. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Sb5+ and one P+4.50+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Sb5+ and one P+4.50+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sb5+ and one P+4.50+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one P+4.50+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one P+4.50+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two P+4.50+ atoms. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one P+4.50+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one P+4.50+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one Sb5+ and one P+4.50+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one P+4.50+ atom. In the eleventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P+4.50+ atoms. In the twelfth O2- site, O2- is bonded in a 2-coordinate geometry to one Sb5+ and one P+4.50+ atom. In the thirteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one P+4.50+ atom. In the fourteenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Sb5+ and one P+4.50+ atom.
