Tris-o-semiquinonato cobalt complexes react with a tetrapodal pyridine-derived ligand to form dinuclear cobalt compounds of general formula (OMP)[CoQ(2)](2), where OMP = 2,2-(pyridine-2,6-diyl)bis(N-1,N-1,N-3,N-3-tetramethylpropane-1,3-diamine), Q = mono- or dianion of 3,6-di-tert-butyl-o-benzoquinone (complex 1) and it derivatives: 3,6-di-tert-butyl-4,5-N,N-piperazino-o-benzoquinone (complex 2), and 3,6-di-tert-butyl-4-Cl-o-benzoquinone (complex 3). Single crystal X-ray crystallography of 1 and 3 indicates two bis-quinonato cobalt units bound by an OMP ligand, which acts as a bridge. Each central cobalt atom is chelated by one N-1,N-1,N-3,N-3-tetramethylpropane-1,3-diamine and two o-quinonato fragments. The nitrogen atom of the pyridine ring is uncoordinated. All complexes were characterized by NIR-IR and EPR spectroscopy, precise adiabatic vacuum calorimetry, and by variable-temperature magnetic susceptibility measurements. All data indicate a reversible thermally driven redox-isomeric (valence tautomeric) transformation in the solid state for all complexes.
