摘要:
Preparation of the terminal nitrido anion (-)[NNb(N[Pr-i]Ar)(3)] and the niobazene trimer {(mu-N)Nb-(N[Pr-i]Ar)(2)}(3) (Pr-i = CH(CH3)(2) or CH(CD3)(2), Ar = 3,5-C6H3Me2) entails cooperative splitting of dinitrogen upon reduction of the heterobimetallic paramagnetic dinitrogen complex (Ar[R]N)(3)Mo(mu-N-2)Nb(N[Pr-i]Ar)(3) (R = Bu-t or C(CD3)(2) CH3).
