abstract
Lithium salts of (dialkylamino)ethylcyclopentadienyl react with either ZnCl2 or Zn(OAc)2 to afford dimeric derivatives containing bridging chlorides or acetates, respectively. X-ray structural determinations of three such derivatives show that the cyclopentadienyl ligands are bound to the zinc centers in an 1 fashion and via their amine groups, thereby leading to a stable six-membered metallacycle.
