摘要 以2,2′-二硫代二苯甲酸为配体,分别与铜(Ⅱ)、钴(Ⅱ)、镍(Ⅱ)合成了三种过渡金属配合物,通过元素分析、ICP发射光谱和热重分析确定了配合物的组成;并用红外光谱、荧光光谱和热重分析进行了表征.结果表明:2,2′-二硫代二苯甲酸与与铜(Ⅱ)、钴(Ⅱ)、镍(Ⅱ)形成摩尔比为1∶1型配合物,三种配合物均具有较强的荧光性能,配合物热稳定性为:镍(Ⅱ)和钴(Ⅱ)高于铜(Ⅱ). Three transition metal complexes of 2,2′-dithiobinary benzoic acid with Cu(II),Ni(II)and Co(II) were synthesized. Their compositions were identified by using elemental analysis,ICP emission spectrometric analysis and thermogravimetric analysis. The structures of the title complexes were assumed by IR analysis,fluorescence spectroscopy and thermogravimetric analysis. The results show that the complexation molar ratio of M(Cu(II),Ni (II) and Co(II)) to 2,2′-dithiobinary benzoic acid is 1:1,the three transition metal complexes have strong fluorescence properties,and thermal stability of complexes of nickel (Ⅱ) and Cobalt (Ⅱ) are higher than that of copper (Ⅱ).
