Abstract
The title complexes are stable, borate-bridged ansa-zirconocene species whi ch have been prepared by reacting [{Ph(SMe2)B(eta(5)-C5H4)(2)}ZrCl2] (1) wi th Cp*(2)-AlMe and [PPN]Cl. Their molecular structures were determined by X -ray diffraction. Noteworthy are the stabilities of the borate-cyclopentadi enyl linkages and the enhanced Lewis acidity of the boron within its strain ed ansa position.
