Terpyridine complexes

the second copper. The difference appears to be that the presence of the additional
chloride in the mononuclear complex leads to a weakening of the axial bridging
interaction.
4. Conclusion
40-(o-Toluyl)-2,20 : 60,200-terpyridine has been prepared and derivatized. This ligand and
its brominated derivative can be used to form metal complexes, although in the latter
case a halogen exchange reaction occurred. 40-[2-(Bromomethyl)phenyl]-2,20 : 60,200-
terpyridine promises to be a useful synthon to allow additional donors to be added to
the terpyridine unit. We plan to introduce groups that can interact with the metal ion
bound to the terpyridine, or that are capable of binding a second metal ion.
