Materials Data on Zn3Te2P2(PbO7)2 by Materials Project
Pb2Zn3Te2P2O14 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share a cornercorner with one ZnO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 76°. There are a spread of Zn–O bond distances ranging from 1.97–2.03 Å. In the second Zn2+ site, Zn2+ is bonded to six O2- atoms to form distorted ZnO6 octahedra that share corners with two equivalent ZnO4 tetrahedra and corners with two equivalent PO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.96–2.60 Å. Pb2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Pb–O bond distances ranging from 2.50–2.95 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one ZnO6 octahedra and corners with two equivalent ZnO4 tetrahedra. The corner-sharing octahedral tilt angles are 35°. There are a spread of P–O bond distances ranging from 1.55–1.58 Å. Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.92–2.52 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Zn2+, one Pb2+, and one Te4+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Zn2+ and two equivalent Te4+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two Zn2+, one Pb2+, and one Te4+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Zn2+, two equivalent Pb2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Zn2+, one Pb2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Zn2+, one Pb2+, and one P5+ atom.
