摘要: 报道9种新的过渡金属[Cr(Ⅲ)、Mn(Ⅱ)、Fe(Ⅲ)、Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)、Zn(Ⅱ)]五苯并咪唑甲基二乙三胺双核配合物的研究。变温磁化率分析结果表明,双核离子间存在反铁磁相互作用。对于二价过渡金属离子,磁交换作用大小为|JCu(Ⅱ).S=1/2|>|JNi(Ⅱ).S=1|>|JCo(Ⅱ).S=3/2|>|JMa(Ⅱ).S=5/2|。对配合物进行了体外抗癌活性和农药活性测定,发现部分配合物具有生物活性。

Abstract: Nine novel dinuclear complexes of transition metal ions with pentabenzimidazolylmethyl diethylene triamine are reported.The results of variable temperature magnetic susceptibility of the complexes indicated that an antiferromagnetic exchnge interaction exists between metal ions in dinuclear unit.Themagnitude of thespin interaction (J) of the complexes had the following sequence|JCu(Ⅱ).S=1/2|>|JNi(Ⅱ).S=1|>|JCo(Ⅱ).S=3/2|>|JMa(Ⅱ).S=5/2|. The preliniinflry rexults of bioassay shwed that some complexeshd antitumor activities in vitro, regulating plant growth and fungicidal activities.
