The synthesis of the macrocyclic tetraimidazolium salt (H4-1)(Br)4 and the anion exchange to (H4-1)(PF6)4 have been explored. Deprotonation of (H4-1)(PF6)4 with Ag2O yields the mono- and dinuclear silver(I) complexes Ag(H2-1)3 and Ag2(1)2. Transmetallation of the dicarbene and tetracarbene ligands to gold(I) yields the mono- and dinuclear gold(I) complexes Au(H2-1)3 and Au2(1)2. The monosilver complex Ag(H2-1)3, featuring two imidazolium moieties, has been deprotonated and used for the synthesis of the tetranuclear silver(I) octacarbene complex {Ag(1)}2Ag24.
探索了大环四咪唑盐（H4-1）（Br）4 的合成以及阴离子交换为（H4-1）（PF6）4。用 Ag2O 脱质子（H4-1）（PF6）4 生成单核和双核银（I）配合物[Ag（H2-1）]（PF6）3 和 [Ag2（1）]（PF6）2。二碳烯和四碳烯配体向金（I）的转金属化生成单核和双核金（I）配合物[Au（H2-1）]（PF6）3 和 [Au2（1）]（PF6）2。具有两个咪唑𬭩部分的单核银配合物[Ag（H2-1）]（PF6）3 已被脱质子化，并用于合成四核银（I）八碳烯配合物[{Ag（1）}2Ag2]（PF6）4。
