摘　　要：乙基黄原酸基的结构为:SSC-O-C_(2)H_(5)(简写为Exan,它是一个双齿配体,能和许多金属离子形成稳定配合物。 本文依据实验结果,对3种Ni(Ⅱ)和2种Zn(Ⅱ)的乙基黄原酸盐混合配合物的性质作一些系统的比较.应用红外光谱讨论这些混合配合物的C—O及C—S键振动频率位移;用热谱讨论它们的热稳定性及失重过程的变化。The mixed complexes of three nickel and two zinc xanthates with pyridine bases were synthesized and characterized by infrared spectra,thermogravimetric(TG), bifferential thermal analyses (DTA), electronic spectra and magnetic susceptibilities. The relationship between their structures and properties are also studied. The thermal stabilities of nickel (or zinc) complexes are in the order.
