Investigation of Mono- and Bimetallic Ruthenium Complexes with the Facial Terminal Ligand Tris(1-pyrazolyl)Methane

Theresa Yi and Matthew T. Mongelli. Kean University, Union, NJ

Ruthenium (II) complexes of the form [(tpm)RuCl(BL)]+ and [{(tpm)RuCl}2(BL)]2+, where tpm = tris(1-pyrazolyl)methane and BL = the bridging ligand dpp (2,3-bis(2-pyridyl)pyrazine) or bpm (2,2'-bypyrimidine), have been synthesized. The terminal ligand tpm has a facial arrangement which should change the properties of the complexes over the more common meridional arrangement seen with the tpy (2,2':2�,6'-terpyridine) terminal ligand. The synthesis, purification and characterization of these complexes will be presented. Comparison of previously known tpy complexes and the newly synthesized tpm complexes will be investigated.
