Reactions of half-sandwich iridium and rhodium complexes [CpMCl2]2 (1a: M = Ir, 1b: M = Rh) and the half-sandwich ruthenium complex [(p-cymene)RuCl2]2 (1c) with 4DPDS gave the corresponding binuclear complexes [{CpMCl2]2}(m-4DPDS) (2a: M = Ir, 2b: M = Rh) and [{(p-cymene)RuCl2]2}(m-4DPDS) (2c), which can be converted into binuclear metallamacrocycles. The metallamacrocycles [Cp*M(m-4DPDS)Cl]2(2+) (3a: M = Ir, 3b: M = Rh) and [(p-cymene)Ru(m-4DPDS)Cl]2(2+) (3c) are composed of two half-sandwich units and two 4DPDS ligands with the same chirality. The macrocycle 3c is chiral and changes its shape slightly depending on the guests accommodated above and below the cavities.
半三明治铱和铑配合物[CpMCl2]2（1a：M = Ir，1b：M = Rh）和半三明治钌配合物[(p-cymene)RuCl2]2（1c）与 4DPDS 的反应生成相应的双核配合物[{CpMCl2}2(m-4DPDS)（2a：M = Ir，2b：M = Rh）和[{(p-cymene)RuCl2}2(m-4DPDS)（2c），它们可以转化为双核金属大环。金属大环[Cp*M(m-4DPDS)Cl]2(2+)（3a：M = Ir，3b：M = Rh）和[(p-cymene)Ru(m-4DPDS)Cl]2(2+)（3c）由两个半三明治单元和两个具有相同手性的 4DPDS 配体组成。大环 3c 是手性的，并且根据腔上方和下方容纳的客体略微改变其形状。
