Bis(Cyclopentadienyl) Nickel Key Features

High stability

Bis(cyclopentadienyl) nickel exhibits extremely high chemical stability in an oxygen-free, anhydrous, inert environment and is not easily decomposed or oxidized, making it suitable for precision material preparation.

Good volatility

Its excellent volatility allows for uniform, controllable chemical vapor deposition at relatively low temperatures, making it ideal for depositing high-purity nickel thin films.

Excellent catalytic activity

As an organometallic nickel source, bis(cyclopentadienyl) nickel is an effective catalyst precursor in cross-coupling reactions such as olefin polymerization and C-C bond formation.

High-purity, controllable process

Wolfa's products undergo vacuum sublimation purification, achieving a purity level above 98%, ensuring reliable performance and contamination-free operation in high-end applications.

Bis(Cyclopentadienyl) Nickel Main Applications

CVD and ALD

Bis(cyclopentadienyl) nickel is used to deposit uniform, dense nickel films due to its high volatility and suitable thermal decomposition temperature, which allows it to decompose into high-purity metallic nickel on the substrate.

Catalyst precursor

NiCp₂ is an important raw material for various nickel catalysts and can be used in olefin polymerization, hydrogenation reactions, and organic synthesis research.

Materials science research

Bis(cyclopentadienyl) nickel is commonly used to study metal-organic ligand bonding patterns, electronic structures, and reaction mechanisms.

Precautions

  1. NiCp₂ is sensitive to moisture and will rapidly oxidize and decompose when exposed to air. Therefore, it needs to be sealed and stored in a light-proof, dry, inert atmosphere (such as argon or nitrogen).

  2. All weighing, sampling and reaction operations should be carried out in a glove box or under the protection of an inert atmosphere. Appropriate personal protective equipment must be worn to avoid direct skin contact.

  3. In case of accidental contact, rinse thoroughly with plenty of water and soap. If you feel unwell, seek medical attention.

  4. Transport must be carried out in secure, sealed containers and protected from high temperatures, impacts and direct sunlight.

  5. All residues and waste materials should be treated as hazardous chemical waste, placed in sealed containers, and entrusted to qualified professional organizations for disposal.

FAQ

1. Can NiCp₂ come into contact with air?

No, it will rapidly oxidize, discolor, and even decompose. It should be handled and stored in an inert atmosphere.


2. Is bis(cyclopentadienyl) nickel dangerous?

It is a flammable solid and irritating to the skin and respiratory tract. It should be used strictly in accordance with the MSDS.
