was reacted with zinc(II) to afford a neutral metal complex [ZnL2Cl2]. The crystal structure analysis of [Co(L1)2] indicate that Co(II) ion is coordinated by six nitrogen atoms from two perpendicular ligands while in [ZnL2Cl2], Zn(II) is coordinated by two chlorine atoms and three nitrogen atoms. The electrochemical behavior indicate that ligands L1 and L2 and the zinc(II) complex are suitable fort the
两种四硫富瓦烯附加吡啶hydr嘧啶配体的合成,即(Z)-4-(2-((5-([[2,2'-bi(1,3-二硫代亚烷基)]-4-基)吡啶-2- yl)亚甲基)肼基)-6-氯嘧啶L1和(Z)-4-(2-((6-([[2,2'-bi(1,3-二硫代亚烷基)]-4-基)吡啶-2-描述了基)亚甲基)肼基)-6-氯嘧啶L2。使配体L1与钴(II)反应以产生阳离子金属配合物[Co(L1)2 ],而使配体L2与锌(II)反应以提供中性金属配合物[ZnL2Cl 2 ]。[Co(L1)2 ]的晶体结构分析表示Co(II)离子由来自两个垂直配体的六个氮原子配位,而在[ZnL2Cl 2 ]中,Zn(II)由两个氯原子和三个氮原子配位。电化学行为表明,配体L1和L2以及锌(II)配合物适合于制备结晶自由基阳离子盐。最后,确定针对白色念珠菌,光滑念珠菌,副念珠菌,克鲁斯氏梭菌和皮肤癣菌的MIC 80值表明,钴(II)金属配合物[Co(L1)2
