Materials Data on Zn4SiTePbO10 by Materials Project
Zn4PbSiTeO10 crystallizes in the orthorhombic Pnma 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 corners with two equivalent TeO6 octahedra, corners with two equivalent SiO4 tetrahedra, and corners with three equivalent ZnO4 tetrahedra. The corner-sharing octahedral tilt angles are 58°. There are a spread of Zn–O bond distances ranging from 1.96–2.05 Å. In the second Zn2+ site, Zn2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Zn–O bond distances ranging from 1.92–2.07 Å. Pb2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Pb–O bond distances ranging from 2.33–3.10 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four equivalent ZnO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.63–1.66 Å. Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with four equivalent ZnO4 tetrahedra. There are a spread of Te–O bond distances ranging from 1.95–1.98 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Zn2+, one Pb2+, and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Zn2+ and one Te6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Pb2+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Zn2+, one Pb2+, and one Te6+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Zn2+, one Pb2+, and one Si4+ atom. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one Te6+ atom.
