Sterically hindered o-quinones functionalized with additional chelating groups were synthesized by the reaction of 3,6-di-tert-butyl-4,5-dichloro-o-benzoquinone with geminal dithiolates. The spin density distribution in reduced anion-radical derivatives of the new compounds was studied by EPR spectroscopy in order to reveal the possibilities of electronic communication between the coordination sites
