Materials Data on Mo3O8 by Materials Project

Abstract

Mo3O8 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two Mo3O8 sheets oriented in the (1, 0, 0) 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 edge-sharing MoO6 octahedra. There is two shorter (1.94 Å) and four longer (1.96 Å) Mo–O bond length. In the second 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 1.92–2.23 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in an L-shaped geometry to two equivalent Mo+5.33+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to three Mo+5.33+ atoms. In the third O2- site, O2- is bonded in a water-like geometry to two Mo+5.33+ atoms.
