structures of the dinuclear nickel(II) and copper(II) complexes with the composition Ni2L2·2AcOH·2MeOH and Cu2L2, respectively, were established by X-ray diffraction. The copper chelates are characterized by the presence of antiferromagnetic exchange interactions. The mononuclear copper(II) complexes (DMSO)bis[2-(5,7-di-tert-butyl-4-hydroxybenzoxazol-2-yl)phenolato]copper(II) and (DMF)2bis[2-(5,7-di-
基于位阻三齿席夫碱的钴 (II)、镍 (II) 和铜 (II) 配合物的化学和电化学合成,通过 2-氨基-4,6-二-叔丁基苯酚与水杨醛衍生物偶联获得(H2L, H2L') 进行。所得双核配合物在 300-2 K 温度范围内通过元素分析、红外光谱和磁化学测量进行表征。通过X射线衍射确定了分别具有Ni2L2·2AcOH·2MeOH和Cu2L2组成的双核镍(II)和铜(II)配合物的结构。铜螯合物的特征在于存在反铁磁交换相互作用。单核铜(II)配合物(DMSO)双[2-(5,7-二叔丁基-4-羟基苯并恶唑-2-基)苯酚]铜(II)和(DMF)2双[2-(5,
