摘　　要：室温下合成了含有二茂铁基的双核铜配合物Cu2 (dmaf) 2 (CH3 COO) 4 (Ⅰ )和Cu2 (dmaf) 2 (C6H5COO) 4(Ⅱ ) [dmaf=(dimethylaminomethyl)ferrocene]。采用扫描电镜半定量测定标题化合物成分 ,用X射线衍射法测试 ,并确定两者的晶胞参数 ,发现两者有相似的晶体结构。最后对标题物的红外、远红外、固体漫反射电子光谱、循环伏安法 (CV)等谱学性质进行深入研究。结果表明 ,两个配合物紫外吸收波段分别为 2 34～2 6 9nm和 2 4 5～ 2 80nm ,在可见光区出现了一个d d跃迁宽域带 ,其循环伏安曲线表明 ,两个化合物的氧化还原电位分别为 0 5 3,0 37和 0 6 2 ,0 36V。Binuclear copper(Ⅱ) complexes containing ferrocenyl Cu_2(dmaf)_2(CH_3COO)_4(Ⅰ) and Cu_2(dmaf)_2(C_6H_5COO)_4(Ⅱ) [dmaf=(dimethylamino-methyl)ferrocene] were synthesized at room temperature.Their chemical constitutions were measured semiquantitatively by scanning electrical mirror (SEM),and their cell parameters were determined by X-ray diffraction,which show that the two complexes have similar crystal structure.The studies on IR,far IR,solid electronic spectrum of diffuse reflection, and cyclic voltammetry(CV) indicate that the two compounds have an UV absorption peak in 234-269 nm and 245-280 nm,respectively,and in the visible range there is a d-d transition wide region.The CV curves indicate that the oxidation-reduction potentials of the two compounds are 0.53,0.37 and 0.62,0.36 V,respectively.
