Abstract:
One‐ and two‐electron oxidized Cu II complexes of Schiff base ligands with para ‐substituted phenolate moieties were synthesized and characterized. The crystal structure of the one‐electron oxidized methylthio‐substituted complex [Cu(MeS‐salen)]SbCl 6 revealed the intermolecular π‐π stacking interaction of the two phenolate moieties with those of the neighboring complex cations to form the one‐dimensional chain. Such a π‐π stacking interaction could not be detected in the two‐electron oxidized complex [Cu(MeS‐salen)](SbCl 6 ) 2 and the oxidized methoxy‐substituted complexes [Cu(MeO‐salen)](SbF 6 ) n ( n =1, 2). Magnetic study of [Cu(MeO‐salen)]SbF 6 showed a weak antiferromagnetic interaction between the Cu II ion and phenoxyl radical unpaired electron spins, while [Cu(MeS‐salen)]SbCl 6 showed a ferromagnetism. Both of the two‐electron oxidized complexes exhibited a relatively strong magnetic interaction between the two radical electrons, while the signs of the electron spins are different.
