Materials Data on Te2MoO7 by Materials Project
MoTe2O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mo6+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Mo–O bond distances ranging from 1.74–2.18 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.92–2.13 Å. In the second Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.89–2.23 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Mo6+ and one Te4+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Te4+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Te4+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two Te4+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Te4+ atoms. In the sixth O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom.
