摘要：

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 Li-12 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.
