Materials Data on Mg2TeWO6 by Materials Project
Mg2WTeO6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mg2+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of Mg–O bond distances ranging from 2.05–2.66 Å. W4+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of W–O bond distances ranging from 1.93–2.00 Å. Te4+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.15 Å) and two longer (2.36 Å) Te–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Mg2+, one W4+, and one Te4+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to one Mg2+, one W4+, and one Te4+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Mg2+ and one W4+ atom.
