Abstract
Reaction of the diamagnetic cluster (TMEDA)(2)Nb2Cl5Li(TMEDA) with the (3,5-Me2Ph)(Ad)NLi (Ad = adamantyl) amide led to a rare case of C-N b ond activation and formation of tetravalent, dinuclear, and diamagneti c {(3,5-Me2Ph)(Ad)N]Nb(3,5-Me2Ph)}(2)(mu-Nad)(2) .-ether (1) containin g a Nb-Nb single bond. Conversely, a similar reaction carried out with [Cy2NLi](4) (Cy = cyclohexyl) yielded dinuclear {[(Cy2N)(2)Nb](2)(mu- N)}(mu(3)-N)Li(TMEDA) (2).
