a C2-symmetric dimer involving four Ni−N interactions and a Ni2N2 core featuring a short Ni−Ni distance (2.51 Å). Preliminary reactivity tests have shown that 5 is stable toward weak nucleophiles such as acetonitrile but reacts with strong nucleophiles such as CO or 2,6-Me2(C6H3)NC. Reactions with protic reagents showed that phthalimide appears to break the dimer to generate a monomeric species, whereas
