Tris (Acetonitrile)  Chromium Tricarbonyl Key Features

Stable structure

The Cr(CO)3 fragment provides the molecule with good electronic stability, allowing Tris(acetonitrile)chromium tricarbonyl to exhibit well-controlled reactivity under organometallic reaction conditions.

Prone to ligand exchange

CH3CN is a weakly coordinating ligand and can be replaced under mild conditions by phosphine, olefin, or aromatic ligands, making it suitable as a precursor for the synthesis of diverse chromium complexes.

Low-valent chromium centers

Cr(0) species exhibit high reactivity, making them suitable for studies involving π-coordination, ligand substitution, and reaction mechanisms. They are commonly used model compounds in organometallic chemistry and catalysis.

Research-friendly

This product is commonly used in laboratory and pilot plant settings, and is suitable for small-batch procurement, customized purity, and stable batch supply.

Precautions

  1. Prolonged exposure to air may lead to ligand detachment or oxidation reactions, affecting product purity and performance; therefore, contact with air and moisture should be avoided.

  2. Avoid high-temperature environments, as high temperatures can cause the dissociation of CO ligands in metal carbonyls, posing safety and stability risks.

  3. It is recommended to wear protective gloves and safety glasses, take personal protective measures, and operate in a well-ventilated environment or under an inert atmosphere.

  4. Strong oxidizing or corrosive substances can damage metal carbonyl structures and should be avoided.

  5. The MSDS (Material Safety Data Sheet) should be read thoroughly before use, and waste materials should be disposed of according to local chemical management regulations.
