hexamolybdenum

Hexamolybdenum is a chemical compound with the formula Mo6O19. It is a dark blue, crystalline solid that is highly insoluble in water. Hexamolybdenum is a polyoxomolybdate, a type of compound that contains molybdenum in a high oxidation state, typically +6, and is characterized by the presence of multiple molybdenum-oxygen bonds.

The compound is often used as a precursor in the synthesis of other molybdenum-containing materials, such as catalysts and pigments. It is also used in the production of molybdenum blue, a pigment used in paints and inks. Hexamolybdenum is typically prepared by the reaction of molybdenum trioxide with a strong oxidizing agent, such as hydrogen peroxide or potassium permanganate, in the presence of a strong acid.

Hexamolybdenum is a strong oxidizing agent and can react with a variety of reducing agents, including organic compounds. It is also known to catalyze certain chemical reactions, such as the oxidation of alcohols to aldehydes or ketones. The compound is stable under normal conditions but can decompose upon heating, releasing oxygen and forming molybdenum oxide.

Hexamolybdenum is not toxic and is generally considered to be a safe compound to handle. However, as with any chemical compound, it should be handled with care and appropriate safety precautions should be taken.
