Dinuclear Tripod Cobalt Complexes with Bridging 1,4,5,8‐Tetraoxonaphthalene and 1,4,9,10‐Tetraoxoanthracene Ligands: Structures, Spectroscopic, Magnetic, and Electrochemical Properties The syntheses, structures, optical, magnetic, and redox properties of dinuclear tripod cobalt(II) complexes [ tripod = CH 3 C(CH 2 PPh 2 ) 3 ] with briding 1,4,5,8‐tetraoxonaphthalene 1 2‐ and 1,4,9,10‐tetraoxoanthracene 2 2‐ are described. UV/Vis/NIR spectroscopy indicates interaction between the ligand and the metal orbitals. The magnetic interactions involving the two cobalt(II) centers and the bridging ligand are characterized by EPR spectroscopy and magnetic measurements and are analyzed in terms of qualitative Molecular Orbital calculations. The redox chemistry of these complexes is investigated by cyclic voltammetry and interpreted as metal‐based oxidations and ligand‐based reductions.
