Abstract
The synthesis of coordination compounds of ruthenium(II) containing the new tridentate ligand 4,4′,4″,-tri-tert- butyl-terpyridine (trpy*) is reported. Trpy* has been prepared in up to 50% yield from tert-butyl-pyridine, and easily separated from 4,4′-di-tert-butyl-bipyridine (bpy*). A series of complexes [(trpy*)(L

3. Individual complexes have been characterized by elemental analyses,
1H NMR and UV-Vis spectroscopies, and cyclic voltammetry.
