Materials Data on Mn2V2O7 by Materials Project

Mn2V2O7 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. V5+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of V–O bond distances ranging from 1.74–2.38 Å. Mn2+ is bonded to six O2- atoms to form distorted edge-sharing MnO6 pentagonal pyramids. There are a spread of Mn–O bond distances ranging from 2.13–2.25 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one V5+ and two equivalent Mn2+ atoms. In the second O2- site, O2- is bonded in a linear geometry to two equivalent V5+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent V5+ and two equivalent Mn2+ atoms.
