A number of Ru(II) complexes, both homo- and heteroleptic, of variously N-substituted 2,6-di(4,5,6,7-tetrahydroindazol-3-yl)pyridines have been prepared from the free ligands or by N-alkylations of Ru-bound, N-H-bearing ligands. Carboxyl-bearing complexes were prepared by hydrolysis of the corresponding esterified complexes. All were characterized by elemental analysis and by their NMR, FAB-MS, and UV-visible spectra, and a selection was additionally submitted to cyclic voltammetry. The fully substituted complexes showed MLCT bands in the 414-424 nm range and E-1/2(3+/2+) values in the +0.83-0.98 V range. Comparisons with data from related complexes are discussed. A heteroleptic dinuclear species was prepared from a CH2-linked bis(tridentate) and found to consist of the like (chiral racemic) diastereomer. It showed a single MLCT band at 416 nm and a single Ru3+/2+ couple at +0.98 V. In the case of N-H-bearing complexes, deprotonation caused the appearance of a less energetic MLCT band and multiple CV waves at lower oxidation potentials. There was also evidence of loss of H-. at negative potentials. A supramolecular 2:1 salt formed between the deprotonated form of the homoleptic complex of 2,6-di(1-(4-carboxyphenyl)-4,5,6,7-tetrahydroindazol-3-yl)pyridine and methyl viologen dication.
