Reaction of [Cp*MCl2]2 with free 2,3-bppz afforded monomeric [Cp*MCl(2,3-bppz)][PF6], whereas the same reaction in the presence of AgPF6 gave dimeric [[Cp*MCl]2(m-2,3-bppz)][PF6]2 (Cp* = h5-C5Me5, M = Rh, Ir). Crystal structure of the monomeric iridium complex features essentially nonplanar 2,3-bppz ligand, coordinated by one of its pyrazine and pyridine nitrogens. The prepd. complexes were investigated by cyclic voltammetry and UV/VIS-spectroelectrochem.
