(Spectro)Electrochemistry of 3-(Pyrid-2-yl)-s-Tetrazine- and 1,2-(Dihydro)pyridazine Tricarbonylrhenium(I)chloride

The electrochemistry and spectroelectrochemistry (SEC) of the three [ReCl(CO)(3)(N N)], N N=3-(pyrid-2-yl)-1,2,4,5-tetrazine [1], 3-(pyrid-2-yl)-4-ferrocenyl-4,5-dihydropyridazine [1H(2)Fc], and 3-(pyrid-2-yl)-4-ferrocenyl-pyridazine [1Fc], are reported. The ligand's conjugation affects the reduction potentials as well as intramolecular charge transfers observed in the UV-vis-NIR spectrum. The spectroscopic observations were further supported by DFT calculations.

Automated summary
