钒（Ⅳ）与N，N，N＇，N″，N″─五苯并咪唑甲基二乙三胺多核配合物合成、ESR和生物活性

SYNTHESIS, ESR AND BIOACTIVITY OF POLYNUCLEAR COMPLEXES OF VANADIUM(Ⅳ) WITH PENTABENZIMIDAZOLYLMETHYL DIETHYLENETRIAMINE

合成了两种新的Ｎ，Ｎ，Ｎ＇，Ｎ″，Ｎ″─五苯并咪唑甲基二乙三胺ＶＯ（Ⅱ）多核配合物并进行了元素分析、ＩＲ、ＵＶ─ｖｉｓ、ＥＳＲ等表征。求得了配合物的自旋Ｈａｍｉｌｔｏｎ参数，两配合物中Ｖ（Ⅳ）的电子环境差别较大。体外抗癌活性和农药活性测定结果表明配合物具有一定生物活性。

Two novel polynuclear complexes of VO(Ⅳ) with N, N,N',N″,N″-pentabenzimidazolylmethyl diethylenetriamine(L) have been synthesized and characterized. The spin Hamilton parameters of the complexes were calculated from ESR spectra. There is great difference between the two complexes in electronic enviroment of vanadium(Ⅳ). The preliminary results of bioaasay showed that the complexes have antitumor activities in vitro, strong herbicidal and fungicidal activities.
