In recent years several bisterpyridine ligands have been utilized for the assembly of a plethora of supramolecules, utilizing the  complex.  Although a variety metal ions have been implemented in this chemistry, typically transition metals ions, such as RuII, OsII, FeII, ZnII, and CdII are used. The lability of the CdII complexes has proven invaluable in the synthesis of simple polygons. In particular, novel metallotriangles will be addressed. Bisterpyridine ligands have been synthesized by a variety of simple known organic transformations. Recent commercial availability of 4-formylphenylboronic acid has paved the way for several novel ligands to be synthesized, based off a central benzene core, with anywhere from 1-6 terpyridine moieties attached. Increasing the complexity of the terpyridine ligands has been shown to give higher ordered structures in high yields. The physical properties of these snowflake structures have been studied, as well as their assembly into even higher ordered nanoarchitectures, via a variety of intermolecular interactions, such as van der Waal and ionic. These novel assemblies will be discussed; also the synthesis and structural characterization will also be considered.
