Abstract

The first complete structurally and spectroscopically characterized series of isostructural Group 6 N₂ complexes is reported. Protonolysis experiments on cis-[M(N₂)₂(P^EtN^RP^Et)₂] (M = Cr, Mo, W; R = 2,6-difluorobenzyl) reveal that only Cr affords N₂H₅⁺ and NH₄⁺ from the reduction of the N₂ ligands.
