Abstrakt

The preparation and molecular structure of meso-(ethylenebis(2-(dimethylamino)indenyl))zirconium dichloride (3) is reported. Predominant meso formation is observed when the ligand dilithium salt is reacted with ZrCl4 in THF. Complex 3 crystallizes in a chiral C-1 symmetric staggered conformation (Ind <^> Ind = 23.1 degrees) and reveals shortened hapto-nitrogen bond lengths, 1.456(11) and 1.399(13) Angstrom, indicating extensive orbital overlap between the nitrogen and the hapto carbon atom.
