Mixed-ligand complexes of the formula Pd(aap)(OO) (5-8), where aap=2-(arylazo)-pyridines and oo=dioxolanes, viz. catechol (CATH2), 4-tert-butyl catechol (TBCATH2), 3,5-di-tert-butylcatechol (DTBCATH2), and 2,3-dihydroxynaphthalene (DHN), were prepared and characterized by elemental analyses, IR, UV-vis and (1)H NMR data. Cyclic voltammograms suggest four successive one-electron responses and are highly sensitive to the nature ofsubstituents. These complexes were found to show a ligand-to-ligand cha rge transfer (LLCT) band. THe position of the LLCT band is largely dependent on the substituent type on the catechol frame and is qualitatively assigned as the 3b1(cat).fwadrw.π*(aap) transition.
