title: Zirconium complexes bearing a tetradentate dipyrrolyl ligand.
abstract: Using a tetradentate, dianionic ligand several new zirconium complexes have been prepared. These pyrrolyl compounds, unlike their titanium analogues, are inactive in hydrohydrazination catalysis. However, they are quite stable, and their reactivity with H2NR, where R = Ph, C6H11, and NHPh, is reported here. Two of the complexes were characterized by X-ray diffraction.
