A novel dodecanuclear manganese metalladiazamacrocycle was synthesized employing a new pentadentate ligand N-2-pentenoylsalicylhydrazide (H3tpeshz) by supramolecular self-assembly. The backbone of this metal-organic assembly is a repeating unit of an M–N–N–M linkage that extends to complete a 36-membered cyclic structure involving 12 manganese(III) centers. Successive manganese centers are in a chemically different ⋯ABABAB⋯-type environment while the chirality varies as ⋯ΛΛΔΔΛΛ⋯. The unique arrangement of manganese centers results in a highly puckered metalladiazamacrocycle with an S6-point group symmetry.
通过超分子自组装,利用一种新的正五价配体 N-2-pentenoylsalicylhydrazide (H3tpeshz),合成了一种新型十二核金属二氮杂环锰。这种金属有机组合物的骨架是一个 M-N-N-M 链接的重复单元,该单元延伸完成了一个包含 12 个锰(III)中心的 36 元环状结构。连续的锰中心处于化学性质不同的 ⋯ABABAB⋯ 型环境中,而手性随着 ⋯ΛΛΔΔΛΛ⋯ 的变化而变化。锰中心的独特排列形成了具有 S6 点群对称性的高度皱褶金属迭氮杂环。
