Materials Data on Te3P2O11 by Materials Project
P2Te3O11 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. 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 TeO5 square pyramids. There are a spread of P–O bond distances ranging from 1.53–1.59 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four TeO5 square pyramids. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. There are three inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Te–O bond distances ranging from 1.86–2.55 Å. In the second Te4+ site, Te4+ is bonded to five O2- atoms to form distorted TeO5 square pyramids that share a cornercorner with one TeO5 square pyramid and corners with two equivalent PO4 tetrahedra. There are a spread of Te–O bond distances ranging from 1.92–2.20 Å. In the third Te4+ site, Te4+ is bonded to five O2- atoms to form distorted TeO5 square pyramids that share a cornercorner with one TeO5 square pyramid and corners with four PO4 tetrahedra. There are a spread of Te–O bond distances ranging from 1.91–2.21 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one P5+ and one Te4+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one P5+ and one Te4+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one P5+ and one Te4+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to three Te4+ atoms. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to two Te4+ atoms. In the sixth O2- site, O2- is bonded in a distorted linear geometry to two Te4+ atoms. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one P5+ and one Te4+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one Te4+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one P5+ and one Te4+ atom. In the tenth O2- site, O2- is bonded in a distorted linear geometry to one P5+ and one Te4+ atom. In the eleventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one P5+ and one Te4+ atom.
