文摘

In basic media, the coordinated semiquinone radical in the spin-coupled [(bipy)ClV^IVO(TCSQ)] 1 (HTCSQ = tetrachlorosemiquinone) undergoes nucleophilic ipso substitution (OH⁻ for Cl⁻) to generate the chloranilate anion (CA²⁻) that bridges the vanadium(IV) centers, forming a binuclear compound [(bipy)ClV^IVO(CA)OV^IVCl(bipy)] 2.
