本文利用2,2',2''-三氨基三乙胺(tren)与二茂铁甲醛(FcCHO)的Schiff碱缩合产物(L)为配体合成了十个三角型过渡金属配合物:[MLX]^2+/1+,M=Zn^2+,Cu^2+,Ni^2+,Co^2+=和MN^2+,X=H~2O或OAc^-,并用电子光谱、红外光谱和顺磁=共振光谱对配合物的结构进行了表征.测定了四个化合物的变温磁化率,实验结果表明二茂铁中磁性的Fe(Ⅱ)离子对配合物的磁性影响很小,整个化合物只显示中心离子的磁性.

A series of tripodal complexes derived from the reaction of 3d transition metal chlorides or acetates (M = Zn2+, Cu2+, Ni2+, Co2+ and Mn2+) with the Schiff base of 2,2',2''-triaminotriethylamine and formylferrocene were prepared and characterized by UV, IR and ESR spectra. Variable temperature magnetic susceptibilities of four typical complexes were measured. Although a large degree of electron delocalization exists in these compounds, the magnetic data indicate that three diamagnetic Fe(II) ions in the ferrocenyl arms have little effect on the magnetism of the complex. The compound only exhibits the magnetic property of the single center ion.

Key words: ZINC COMPLEX, COPPER COMPLEX, PARAMAGNETIC RESONANCE, COBALT COMPLEX, TRANSITION METAL COMPLEX, NICKEL COMPLEX, SCHIFF BASE, MANGANESE COMPLEX, ELECTRON SPECTROMETRY, FERROCENE P
