Molybdenum hexacarbonyl, also known as hexacarbonylmolybdenum or molybdenum carbonyl, is a solid, white powder or crystalline substance with the molecular formula Mo(CO)₆ and a molecular weight of 264 g/mol. This compound, with a purity of over 98% as determined by titration, is widely used in organometallic chemistry and materials science due to its reactivity and ability to serve as a source of molybdenum in various chemical reactions.
Molybdenum hexacarbonyl appears as white powder or crystals and has a melting point of 150°C and a boiling point of 156°C. It is relatively stable under standard conditions but should be handled and stored with care. While the compound is generally solid at room temperature, it can decompose upon heating, releasing toxic carbon monoxide gas. Therefore, it is recommended to store it in a cool, dry place, away from sources of heat, to maintain its stability.
This compound is often used as a precursor in the preparation of molybdenum-containing catalysts, which are essential in various industrial chemical processes, including hydrocarbon cracking and organic synthesis. Its ability to break down into molybdenum metal or other reactive species makes it highly valuable in chemical vapor deposition (CVD) processes for thin-film coatings in electronics and other high-tech applications. Additionally, molybdenum hexacarbonyl serves as a useful reagent in the synthesis of other molybdenum-based compounds.
Molybdenum hexacarbonyl poses several health hazards, including acute toxicity if ingested (H300), absorbed through the skin (H310), or inhaled (H330). Due to its ability to release carbon monoxide, a highly toxic gas, it requires careful handling in well-ventilated areas or under fume hoods. Protective clothing, gloves, and respiratory protection are essential when working with this substance to avoid exposure and potential health risks.
Molybdenum hexacarbonyl, also referred to as hexacarbonylmolybdenum or molybdenum carbonyl, is a versatile compound used in various industrial applications, particularly as a catalyst precursor and in advanced material synthesis. However, its toxicity and potential for hazardous decomposition require stringent safety measures during handling and storage.
Molybdenum hexacarbonyl, due to its ability easily vaporized and decomposed by the electron beam, is widely used in electron beam-induced deposition technique. It is used as a reagent in organometallic synthesis because of the displacement of carbonyl ligands by other donor ligands. This product also utilized as a precursor for the manufacture of organomolybdenum dyes and for Molybdenum plating by thermal decomposition. In organic synthesis, its derivatives are employed as catalysts.
