Bis(4,7-dimethylindenyl)zirconium dichloride

Description:
Bis(4,7-dimethylindenyl)zirconium dichloride, with the CAS number 130408-22-9, is a transition metal complex that features zirconium as the central metal atom coordinated to two 4,7-dimethylindenyl ligands and two chloride ions. This compound is notable for its role as a catalyst in olefin polymerization, particularly in the production of high-performance polymers. The presence of the bulky 4,7-dimethylindenyl ligands enhances the steric and electronic properties of the zirconium center, allowing for improved catalytic activity and selectivity. Typically, it exhibits a high thermal stability, making it suitable for various polymerization processes. The dichloride form indicates that it has two chloride ions, which can be replaced by other ligands or solvents in catalytic reactions. Overall, this compound is significant in the field of organometallic chemistry and materials science, particularly in the development of advanced polymeric materials.
