Popis:	The title complexes are stable, borate-bridged ansa-zirconocene species which have been prepared by reacting [{Ph(SMe2)B(η5-C5H4)2}ZrCl2] (1) with Cp*2AlMe and [PPN]Cl. Their molecular structures were determined by X-ray diffraction. Noteworthy are the stabilities of the borate−cyclopentadienyl linkages and the enhanced Lewis acidity of the boron within its strained ansa position.
