Materials Data on Zn2TeMoO7 by Materials Project
Zn2TeMoO7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with three equivalent ZnO6 octahedra and a cornercorner with one ZnO4 tetrahedra. The corner-sharing octahedra tilt angles range from 32–59°. There are a spread of Mo–O bond distances ranging from 1.79–1.82 Å. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four O2- atoms to form distorted ZnO4 tetrahedra that share corners with three equivalent ZnO6 octahedra and a cornercorner with one MoO4 tetrahedra. The corner-sharing octahedra tilt angles range from 40–60°. There are a spread of Zn–O bond distances ranging from 1.96–2.01 Å. In the second Zn2+ site, Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with three equivalent MoO4 tetrahedra and corners with three equivalent ZnO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 2.04–2.21 Å. Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.91–2.58 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two Zn2+ and one Te4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Zn2+ and one Te4+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Mo6+, one Zn2+, and one Te4+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Zn2+ and one Te4+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo6+ and one Zn2+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Zn2+ atom. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Zn2+ atom.
