New tetrapyridylethanes can be prepd. as new tetradentate pyridine ligands via the aminolysis reaction of pyrylium dications, using an original oxidn. process of phenylpyridyl methylenepyrans. Crystal structure anal., and spectroscopic and electrochem. studies show the possibility for using these new ligands in coordination chem.
