Decamethylzirconocene dichloride is an organozirconium compound with the formula Cp*2ZrCl2 (where Cp* is C5(CH3)5, derived from pentamethylcyclopentadiene). It is a pale yellow, moisture sensitive solid that is soluble in nonpolar organic solvents. The complex has been the subject of extensive research. It is a precursor to many other complexes, including the dinitrogen complex [Cp*2Zr]2(N2)3).[1] It is a precatalyst for the polymerization of ethylene and propylene.[2]
