MO6

MO6 is an alphanumeric designation used in several unrelated domains. The term does not refer to a single object or concept, but to different items depending on the field.

In inorganic chemistry and materials science, MO6 commonly denotes a six-atom molybdenum cluster. The six molybdenum atoms form a compact core, often adopting octahedral or related geometries, and are stabilized by surrounding ligands such as chalcogenides (sulfur, selenium, tellurium), halides, or organic donors. These high-nuclearity clusters exhibit metal–metal bonding and delocalized electron density, and they are studied as models for fundamental bonding in metal clusters as well as potential precursors to catalytic materials and solid-state molybdenum sulfide or oxide phases. Typical synthetic routes involve assembling molybdenum precursors under reductive conditions and carefully chosen ligands; characterization relies on X-ray crystallography, UV-visible spectroscopy, and electrochemical techniques.

In U.S. road designations, MO-6 or MO 6 may refer to Missouri Route 6, a state highway designation used on maps and signage in Missouri. Route numbers can change over time due to rerouting or decommissioning, so exact endpoints vary by year.

In computational chemistry contexts, the label M06 (not MO6) is a widely used density functional in the Minnesota functionals family. If MO6 appears, it may be a typographical variant or misreading of M06 and should be interpreted accordingly.
