and 2167095 (III)). According to the XRD results and magnetic and spectral measurement data, compounds I–III are complexes of low-spin cobalt(III) bound to two radical anion o-semiquinone ligands and one formazan anion. The magnetic behavior of the complexes in a temperature range of 2–300 K is characterized by intramolecular antiferromagnetic exchange interactions between the o-semiquinone ligands
