N2 - Abstract: The binuclear oxidovanadium(IV) complex [VO(Dbbpy)Cl(Ca)Cl(Dbbpy)VO] (I) is synthesized by the reaction of [VO(Dbbpy)(H2O)Cl2] (Dbbpy is 4,4'-di-tert-butyl-2,2'-bipyridyl) with chloranilic acid H2Ca in acetonitrile in the presence of Et3N in a yield of 79%. Complex I is reduced at Е1/2 = –842 mV (vs. Ag/AgCl), which is shown by cyclic voltammetry for a solid sample using the paste electrode. The EPR spectra and magnetochemical measurements for complex I confirm the existence of two paramagnetic vanadium(IV) centers with the total spin S = 1 and the antiferromagnetic character of the exchange interaction between the centers.
