摘要：

Redox-active ligand H(4)Pra(edt(AP/AP)) experienced C-S bond cleavage during complexation reaction with Co(OAc)(2)center dot 2H(2)O in the presence of Et3N in CH3OH in air. Thus, formed complex 1 was composed of two iminobenzosemiquinone radicals in its coordination sphere and an unprecedented stable tethered-vinyl radical. The complex has been characterized by mass, X-ray single crystal, X-band EPR, variable-temperature magnetic moment measurements and DFT based computational study.
