Abstract
Abstract The preparation of tris(1-methyl-3-(pyridin-2-yl)- 1,2,4-triazole)ruthenium(II) hexafluorophosphate is described. The separation of facial and meridional isomers has been achieved through crystallisation methods. The isomers can be clearly distinguished by their 1 H NMR and 13 C NMR spectra. NMR evidence suggests that the triazole ring is bound to the central metal atom by the N4 donor atom. The title compound does not show any emission at room temperature or liquid nitrogen temperature. Electrochemical data suggest that the ligand (1-Mepytr) is a weaker π-acceptor than 2,2′-bipyridine, but has strong σ- donor properties.
