Give me five! Terdentate 2,6-diamidopyridyl ligands were used to stabilize the Cr-Cr quintuple bond and have made it possible to isolate and characterize not only the Cr-Cr quintuple-bonded complex, but also the mixed-valent intermediates (Cr(I) and Cr(II)), which are important species in the formation of type I quintuple-bonded complexes.
击掌！使用具有齿状结构的 2,6-二氨基吡啶配体稳定了 Cr-Cr 五重键，不仅使 Cr-Cr 五重键配合物能够被分离和表征，而且使混合价态的中间体（Cr(I) 和 Cr(II)）也能够被分离和表征，这些中间体在 I 型五重键配合物的形成中是重要的物种。
