| 摘要: 在弱碱性条件下，双核钌（Ⅲ）配合物Ru2（DMBA）4（NO3）2（DMBA=tetrakis-N，N'-dimethylbenzamidinate）与不同芳香炔反应（其中芳香基团包括：NAPme，N-甲基-1，8-萘二甲酰亚胺；NAPiso，N-异丙基-1，8-萘二甲酰亚胺；Naphth，萘；Ant，蒽），制备了相应的端基炔取代配合物trans-Ru2（DMBA）4（C2Ar）2（Ar=NAPme，1；NAPiso，2；Naphth，3；Ant，4）。利用X射线晶体衍射测定了它们的结构。所有化合物的Ru-Ru 键长处于单键范围（0.245 0~0.249 1 nm），它们均是抗磁性物质。进一步通过1H NMR和UV-Vis-NIR光谱进行了表征。电化学研究表明，所有化合物显示出与芳香基团有关的2个可逆的单电子氧化还原过程（包括一个氧化过程和一个还原过程）。 |

| Abstract: Under weak base conditions, diruthenium(Ⅲ) tetrakis-N,N'-dimethylbenzamidinate (DMBA) nitrate Ru2(DMBA)4(NO3)2 was reacted with arylethyne ligands, where aryl=NAPme (N-methyl-1,8-naphthalimide), NAPiso (N-isopropyl-1,8-naphthalimide), Naphth (naphthalene) and Ant (anthracene), to afford four new compounds: trans-Ru2(DMBA)4(C2Ar)2 (Ar=NAPme, 1; NAPiso, 2; Naphth, 3; Ant, 4). Molecular structures of new compounds were determined using single crystal X-ray diffraction, and the Ru-Ru bond lengths (0.245 0~0.249 1 nm) are consis-tent with the existence of a Ru-Ru single bond. These compounds are diamagnetic and were further characterized with 1H NMR and UV-Vis-NIR spectroscopic techniques. Cyclic voltammograms of compounds 1~4 consist of two reversible one-electron processes, an oxidation and a reduction, and their potentials depend on the nature of Ar. |
