Materials Data on VAgTeO5 by Materials Project
VAgTeO5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. V5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of V–O bond distances ranging from 1.68–1.85 Å. Ag1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ag–O bond distances ranging from 2.44–2.96 Å. Te4+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Te–O bond distances ranging from 1.94–2.82 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ag1+ and two equivalent Te4+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one V5+ and two equivalent Ag1+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one V5+, two equivalent Ag1+, and one Te4+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one V5+, one Ag1+, and two equivalent Te4+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one V5+, one Ag1+, and one Te4+ atom.
