In the fourth chapter, four new complexes of hydrazide of podophyllic acid with transition metals have been prepared. Elemental analysis, molar conductivity, IR,〓 NMR and TG-DTA were used to characterize them. The results show that general formula of the complexes is M〓(n=0 or 2). The ligand is linked through the carbonyl oxygen and the terminal nitrogen of the hydrazide base to the transition metal ions in bidentate mode.

第四章 合成了四种鬼臼酰肼的过渡金属配合物，通过元素分析、摩尔电导、红外光谱、核磁共振氢谱和热重-差热对配合物进行了表征，研究结果表明，配合物的组成为M〓（n=0或2），配体是通过羰基氧和肼基上的端氮以双齿形式与金属离子配位的。

Benzaldehyde nitrogen mustard isonicotinoyl hydrazone was synthesized according to literature method. The copper , cobalt , nickel , chromium , iron , zinc and cadmium complexes of it were prepared and characterized by elemental analysis, IR, UV-vis, NMR and EPR spectra. The cytotoxicity effect of the complexes was examined on SMMC-7721 cell line. Results show that the complexes have definite antitumor activity and the synergic effect between chromium and the ligand.

依照文献合成了异烟肼苯甲醛氮芥腙及其铜、钴、铬、镍、铁、锌和镉配合物并用元素分析、红外、电子光谱、核磁共振及电子顺磁共振光谱，对这些配合物进行表征，确认了它们可能的立体结构，并研究它们对SMMC-7721人肝癌细胞的作用，结果表明它们均有一定的抗肿瘤作用，发现铬与配体存在有协同作用。
