Two interlocked organometallic macrocycles make up the complex ion [FeAg 2 L 2 ] 4+ ( 1 ). The [2]catenate structure forms by quantitative self‐assembly of two ligand strands L and Fe II and Ag I ions. The Fe II center coordinates the tridentate subunits in a pseudooctahedral fashion, the Ag I ions the bidentate subunits in a pseudotetrahedral fashion. Since the two bidentate units of each strand L are coordinated to the same Ag I center, homo‐ and heterochiral isomers of 1 arise.
