在这项工作中合成了新的Ni(II),Cu(II)和Sn(II)Schiff碱配合物。通过元素分析,FT-IR,UV-Visible,1 H NMR和13 C NMR光谱,电导分析,磁测量和热重分析对新配合物进行表征。发现该配体表现为二元二齿,其通过两个去质子化的羟基与金属中心配位,与Ni(II)形成四面体配合物,与Cu(II)形成八面体配合物。该配体通过偶氮甲氮和噻唑硫充当中性双齿,与Sn(II)形成八面体络合物。评价合成的配合物作为使用H 2 O 2氧化靛蓝胭脂红染料的催化剂作为氧化剂,确定催化剂的效率。25分钟后,铜络合物显示出最佳的催化作用,效率为92.17%。

form tetrahedral complex with Ni(II) and octahedral complex with Cu(II). The ligand acts as neutral bidentate through azomethine nitrogen and thiazol sulfur to form octahedral complex with Sn(II). The synthesized complexes are evaluated as catalysts for oxidative degradation of indigo carmine dye using H2O2 as oxidant and the efficiency of the catalysts is determined. The copper complex shows the best

cyanomethyl hydrazone derivatives beside the bishydrazine derivative. Elementary and spectroscopic measurements were in good accord with the structures postulated for the new compounds. The antitumor activities of certain selected new compounds were screened, in vitro, against a panel of four (liver, HepG2; breast, MCF-7; lung, A549; and colon; HCT116) human solid tumor cell lines. The cells that showed
