Abstract
Over the past two decades, polypyridyl complexes of d6 metal ions, owing to their peculiar electrochemical and photophysical properties, have received great attention. In particular, even though a wide range of nitrogen rich aromatic ligands have been employed in the design of mono and dinuclear ruthenium complexes, tetrazole compounds have been only rarely considered in such kind of chemistry. Thus, as the extension of some previous studies,[1] we now report our results about the synthesis and the characterization of new mono and dinuclear Ru(II) polypyridyl complexes containing various 5-substituted tetrazolate ligands. A complete survey of the main coordinative, electrochemical and structural features of these complexes will be discussed as well as some interesting results about their light emitting properties.[2] References [1] Palazzi, A.; Stagni, S.; Bordoni, S.; Monari, M.; Selva, S.
