Evidence of significant halogen bonding interactions.

Potential for creating new supramolecular architectures.

Abstract

We present the synthesis and characterization of (15-crown-5)BiI$_3$ (1) and (15-crown-5)BiI$_3$*0.5TIE (2), a halogen bonded adduct with tetraiodoethylene (TIE), a typical halogen bond donor. Our results show that crown ether complexes of main group metal halides can be employed as halogen bond acceptors for the synthesis of new supramolecular aggregates and highlight the significant interaction between the two building blocks.
