Abstract

Reaction of di-2-pyridyl ketone (dpk) with nickel acetate and azide in the presence of potassium tert-butylate as a catalytic base generates the title compound, which contains the largest [Ni(μ_1,1-N₃)]₆ circles in the discrete ferromagnetically-coupled M^II–azide cluster family, and shows an unprecedented in situ cyanomethylation of ketone.
