Dilithiation of 2-methylpyridine followed by PhCN insertion affords the complex {[C5H4N·CHC(Ph)N]2-·2Li+}6·(THF)4, 5. The crystal structure of 5 reveals an unusual Li12 aggregate containing four types of Li+ cation and two types of dianionic ligand which bond to the metal centres via exclusively N-Li interactions or via combinations of C-Li and N-Li coordinations.
