摘要

Three cobalt complexes, [LCo(μ-Cl)]₂·THF· Et₂O (1), [LCo(η⁶-toluene)] (2), and [LCo]₂ (3), where L = [(2,6-iPr₂C₆H₃)NC(Me)] ₂, have been synthesized from reduction of the dichloro cobalt precursor [LCoCl₂] by sodium or potassium metal. Single-crystal X-ray diffraction analyses reveal that the complexes display novel structures with the singly reduced form (L^•-) of the α-diimine ligand: the dichloro-bridged binuclear complex 1, the mononuclear 2 with an η⁶-coordinated toluene molecule, and the dimer 3 through Co-aryl interactions of two [LCo] units. The compounds were further characterized by EPR and magnetic studies.
