amine), bpqa (bis(2-pyridylmethyl)(2-quinolylmethyl)amine) and pbqa ((2-pyridylmethyl)bis(2-quinolylmethyl)amine) were synthesized as terminal ligands of the tetracoordinated tripod type. In total, six dinuclear Co complexes were synthesized from these biscatechol and terminal ligands as follows: [Co2(L1)(tpa)2](BF4)2 (1), [Co2(L1)(bpqa)2](PF6)2 (2), [Co2(L1)(pbqa)2](PF6)2 (3), [Co2(L2)(tpa)2](BF4)2 (4)
摘要两种双儿茶酚分别为H4L1(5,5'-(buta-1,3-diyne-1,4-diyl)bis(3-t-butylcatecholchol))和H4L2(5,5'-(ethyne-1)合成了(2-二基)双(3-叔丁基邻苯二酚)。在这些配体中,两个氧化还原活性邻苯二酚部分通过一个或两个三键连接。另外,合成了tpa(三(2-吡啶基甲基)胺),bpqa(双(2-吡啶基甲基)(2-喹啉基甲基)胺)和pbqa((2-吡啶基甲基)双(2-喹啉基甲基)胺)作为末端配体。四坐标三脚架类型。从这些双儿茶酚和末端配体总共合成了六种双核Co配合物,如下所示:[Co2(L1)(tpa)2](BF4)2(1),[Co2(L1)(bpqa)2](PF6)2 (2),[Co2(L1)(pbqa)2](PF6)2(3),[Co2(L2)(tpa)2](BF4)2(4),[Co2(L2)(bpqa)2] (PF6)2(
