Abstract

A novel bis(phosphinoalkyl-thioether)arene ligand with a fluorinated aryl group (1,4-(Ph2PCH2CH2S)2C 6F4) has been synthesized. This ligand has been used to prepare symmetric bimetallic structures with RhI and IrI metal centers in high yield. Unlike their nonfluorinated counterparts, these complexes can be opened into large macrocyclic structures through straightforward ligand (i.e., carbon monoxide, nitriles, and isocyanides) substitution reactions at the metal-thioether linkage. In addition, the symmetric bimetallic structures have been shown to react with appropriately sized bifunctional aromatic molecules to form three-tiered host-guest structures.
