摘要: 在弱碱性条件下,双核钌(Ⅲ)配合物Ru2(DMBA)4(NO32(DMBA=tetrakis-NN'-dimethylbenzamidinate)与不同芳香炔反应(其中芳香基团包括:NAPmeN-甲基-1,8-萘二甲酰亚胺;NAPisoN-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=NAPme1;NAPiso2;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.
