MoO6containing

MoO6-containing refers to compounds that include MoO6 octahedra, i.e., six-coordinate molybdenum centers bound to oxide ligands. In these materials, molybdenum is typically in the +6 oxidation state. The MoO6 octahedra commonly link through shared corners or edges to form a variety of structural motifs, including one-, two-, and three-dimensional networks. This class includes simple oxides such as MoO3, layered materials, framework oxides, and discrete polyoxometalate clusters built from MoO6 units.

In MoO3, for example, MoO6 octahedra share edges and corners to create layered sheets; many other MoO6-containing materials extend these motifs into 2D or 3D architectures. Polyoxometalates containing MoO6 units, such as isopolymolybdate clusters, assemble finite molecules built from MoO6 octahedra, which can act as catalysts or redox-active components.

Properties of MoO6-containing materials depend on connectivity and oxidation state, but they often exhibit wide band gaps, and catalytic activity for oxidation reactions. MoO6-containing materials are studied for catalysis, electrochromism (notably in MoO3-based coatings), sensing, and energy-storage applications.

Characterization typically uses X-ray diffraction to determine structure, Raman and IR spectroscopy to identify Mo–O vibrations, and electron microscopy to resolve morphology. Synthesis methods include solid-state synthesis, hydrothermal/solvothermal routes, and sol–gel processing, often followed by heat treatment to obtain the desired phase.
