Pentamethylcyclopentadienylhafnium trichloride

Description:
Pentamethylcyclopentadienylhafnium trichloride, with the CAS number 75181-08-7, is a coordination compound featuring hafnium, a transition metal, coordinated to a pentamethylcyclopentadienyl ligand and three chloride ions. This compound is characterized by its unique structure, where the pentamethylcyclopentadienyl group acts as a strong σ-donor, enhancing the stability of the hafnium center. It typically appears as a solid at room temperature and is known for its volatility, making it useful in chemical vapor deposition processes, particularly in the fabrication of thin films in semiconductor applications. The presence of the trichloride moiety contributes to its reactivity, allowing it to participate in various chemical transformations. Additionally, this compound is of interest in organometallic chemistry due to its potential applications in catalysis and materials science. Safety precautions are necessary when handling this compound, as it may pose health risks if inhaled or ingested, and proper storage conditions should be maintained to ensure stability.
