Molybdenum Chemistry: Complexes, Isotopes, and Compounds
Feb 22, 2024
Coordination Chemistry
Molybdenum is capable of forming stable complexes and bonding with other atoms or molecules via covalent or ionic bonds. These complexes have important applications in fields such as catalysis, organic synthesis, and materials science, and provide the basis for the design of new functional materials. Molybdenum compounds play a central role in industrial catalysis, for example in hydrodesulfurization and oxidation reactions.
Isotopes
Molybdenum (Mo) is a metallic element with abundant isotopes, of which the stable isotopes include Mo-92, Mo-94, Mo-95, Mo-96, Mo-97, Mo-98, and Mo-100, each occupying a portion of the molybdenum in nature. The nuclear composition of these stable isotopes provides the basis for applications from stable isotope tracing to materials analysis. At the same time, molybdenum has a number of radioisotopes, such as Mo-99, which play a role in areas such as medical imaging, nuclear reactions, and radiotracing. Mo-99 decays to technetium-99m, the most widely used isotope in diagnostic nuclear medicine.
Key Compounds
Important molybdenum compounds include molybdenum disulfide (MoS2), a solid lubricant; molybdenum trioxide (MoO3), the main intermediate in molybdenum processing; and molybdates such as ammonium heptamolybdate, used in catalysts, pigments, and fertilizers.
