新型过渡金属配合物合成、磁性和生物活性

Syntheses, Magnetic Properties and Bioactivities of Transition Metal Binuclear Copmplexes

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．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。

Nine novel dinuclear complexes of transition metal ions with pentabenzimi-dazolylmethyl diethylene triamine are reported.The results of variable temperature magneticsusceptibility of the complexes indicated that an antiferromagnetic exchnge interaction ex-ists between metal ions in dinuclear unit.Themagnitude of thespin interaction(J ) of thecomplexes had the following sequence;The preliniinflry rexults of bioassay shwed that some complexeshd antitumor activities invitro, regulating plant growth and fungicidal activities.
