Abstract
The first examples of thermally stable molecular dihydrogen adducts of nickel were synthesized from their dinitrogen adduct precursors, which are themselves among the first examples of Ni(II)-N_2 complexes. The minimal activation of the bound N_2 moieties suggests that these adducts are stabilized predominantly through σ-donation from the adduct to the electrophilic metal center. We further show that the bound H_2 ligand can undergo heterolytic cleavage to deliver hydride to the nickel center. The H_2 adducts are of particular interest in the context of hypotheses suggesting that Ni can serve as the site for H_2 binding and heterolytic activation in [NiFe] hydrogenases.
