新型Schiff碱单核配合物的合成及光谱特征

首次报道了新型Schiff碱配合物-双[N,N'-亚乙基-2,2'-(苯亚甲基)二(3,4-二甲基吡咯-5-醛缩亚胺)]合单金属配合物MH~2[M-Mn(Ⅱ)、Fe(Ⅲ)Cl、Cr(Ⅲ)Cl、Cu(Ⅱ)、Co(Ⅱ)、Ni(Ⅱ)、Zn(Ⅱ)的合成方法及光谱特征。

Studies on the syntheses and spectral character istics of new schiff base mononuclear complexes

The syntheses of bis[N,N'-ethylene-2,2'-(phenylmethylene)bis(3,4- dimethyl pyrrole-5-aldimino)]monometallic complexes MH~2L[M=Mn(Ⅱ), Fe(Ⅲ)Cl, Cr(Ⅲ)Cl, Cu(Ⅱ), Co(Ⅱ), Ni(Ⅱ), Zn(Ⅱ)] were first described. Their spectral characters and configurations were also discussed. The monometallic complexes were preapred by the reaction of ethylenediamine with another series of Schiff base mononuclear complexes, derived by the reaction of the appropriate metal salts with a Schiff base ligand. The Schiff base ligand was prepared from the [1+2] condensation of ethylenediamine with 2,2'-(phenylmethylene) bis(3,4-dimethylpyrrole-5-carboxy- aldehyde).
