Description	New metallocene dichlorides [eta(5)-(1,4-Me-2-2,3-Ph-2-C5H)(2)TiCl2] (2), [eta(5)-(1,4-Me-2-2,3-Ph-2-C5H)(2)ZrCl2] (3) and [eta(5)-(1,4-Me-2-2,3-Ph-2-C5H)eta(5)-(C5H5)ZrCl2] (4) were prepared from lithium salt of 1,4-dimethyl-2,3-diphenylcyclopentadiene (1) and [TiCl3(THF)(3)], [ZrCl4] and [eta(5)-(C5H5)ZrCl3(DME)], respectively. Compounds 2-4 were characterized by NMR spectroscopy, EI-MS and IR spectroscopy, and the solid state structure of 3 was determined by single crystal X-ray crystallography. The catalytic systems 3/MAO and 4/MAO were almost inactive in polymerization of ethylene at 30-50 degrees C, however, they exhibited high activity at temperature 80 degrees C. The catalyst formed from 2 and excess of MAO was practically inactive at all temperatures.
