acts as neutral bidentate, coordinating to the metal ion through the carbonyl oxygen and azomethine nitrogen. Molar conductance values adequately support the electrolytic nature of the complexes. On the basis of the above observations the complexes have been formulated as [M(ISAP)2]X2, where M=Mn(II), Co(II), Ni(II), Cu(II) and Zn(II); X=Cl, OAc; ISAP=2-[N-indole-2-one]aminopyrimidine. The ligand and copper(II)
合成并通过元素分析表征了由Isatin与2-氨基嘧啶缩合形成的锰(II),钴(II),镍(II),铜(II)和锌(II)与席夫碱的配合物,摩尔电导率测量,磁化率,IR,UV-Vis,(1)HNMR,FAB质量和EPR光谱研究。光谱数据表明,该配体充当中性双齿,通过羰基氧和甲亚胺氮与金属离子配位。摩尔电导率值足以支持配合物的电解性质。基于上述观察,将配合物配制成[M(ISAP)2] X 2,其中M = Mn(II),Co(II),Ni(II),Cu(II)和Zn(II)。X = Cl,OAc; ISAP = 2- [N-吲哚-2-一]氨基嘧啶。对配体和铜(II)配合物进行了X射线衍射研究。通过凝胶电泳法监测DNA切割研究。配体和金属络合物的超氧化物歧化酶(SOD)模拟活性使用NBT分析进行了检查。已经测试了合成化合物对革兰氏阴性和革兰氏阳性细菌的体外抗菌活性。
