Materials Data on Mo3O8 by Materials Project

Mo3O8 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two Mo3O8 sheets oriented in the (0, 0, 1) direction. there are two inequivalent Mo+5.33+ sites. In the first Mo+5.33+ site, Mo+5.33+ is bonded to six O2- atoms to form distorted edge-sharing MoO6 octahedra. There are a spread of Mo–O bond distances ranging from 1.88–2.27 Å. In the second Mo+5.33+ site, Mo+5.33+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.80–2.38 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to two Mo+5.33+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent Mo+5.33+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Mo+5.33+ atoms. In the fourth O2- site, O2- is bonded in a water-like geometry to two Mo+5.33+ atoms. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to three Mo+5.33+ atoms. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to three Mo+5.33+ atoms.
