Abstract
The synthesis and characterization of the unsymmetric hafnium dialkyl [1-(e ta(5)-9-fluorenyl)-2-(eta(5)-1-indenyl) ethane]HfCl2 (2) and corresponding dimethyl complex [1-(eta(5)-9-fluorenyl)-2-(eta(5)-1-indenyl)ethane]Hf(CH3) (2) (3) is described. The dialkyl hafnocene (3) crystallizes in monoclinic space group P2(1)/c (No. 14) with a = 9.458(8), b = 8.541(8), c = 23.733(11 ) Angstrom, beta = 93.16(5)deg., V = 1914(3) Angstrom(3) Z = 4. Further on, complex 3 was activated with methylaluminium-oxane (MAO) and utilized as a catalyst in ethene polymerization.
