  ansa-complexes, containing 2-isopropyl-4-arylindenyl and 2-methyl-4-aryltetrahydroindacenyl fragments, have been synthesized. These complexes demonstrate better catalytic activity, stereoselectivty, and polymer molecular weight capability in propylene homo- and copolymerization in comparison to analogues without a tetrahydroindacenyl fragment.
