Coordination of Al(C₆F₅)₃vs. B(C₆F₅)₃ on group 6 end-on dinitrogen complexes: chemical and structural divergences

Abstract

Group 6 metal/Al(C6F5)3 donor–acceptor systems for N2 activation surprisingly diverge from their B(C6F5)3 analogues, providing access to M{NN(Al(C6F5)3)}2 adducts. Implications for the N2 ligand are explored spectroscopically and computationally.
