Abstract

original image

Two interlocked organometallic macrocycles make up the complex ion [FeAg2L2]4+ (1). The [2]catenate structure forms by quantitative self-assembly of two ligand strands L and FeII and AgI ions. The FeII center coordinates the tridentate subunits in a pseudooctahedral fashion, the AgI ions the bidentate subunits in a pseudotetrahedral fashion. Since the two bidentate units of each strand L are coordinated to the same AgI center, homo- and heterochiral isomers of 1 arise.
