A hexabenzimidazole ligand was synthesised and used to prepare a hexakis{benzimidazole-ruthenium(II)} complex containing six RuCl(2)(arene) units of which the X-ray structure analysis shows a helical arrangement with alternating up and down benzymidazole-ruthenium(II) branches attached to a central benzene ring. The reactivity of the prepared complex with phosphite and carbonate was investigated and revealed the weakness of (benzimidazole)N-Ru bonds and the release of the polydentate ligand.
合成了一种六元苯并咪唑配体，并用于制备六[苯并咪唑-钌(II)]配合物，其中包含六个 RuCl(2)(芳烃)单元，其 X 射线结构分析表明，具有交替的上下苯并咪唑-钌(II)支链的螺旋排列，连接到中心苯环上。研究了制备的配合物与亚膦酸酯和碳酸盐的反应性，揭示了(苯并咪唑)N-Ru 键的弱点和多齿配体的释放。
