摘　　要：Cis-diaminedithiocyanatoplatinum(Ⅱ)(cis-[Pt(SCN)2(NH3)2])was prepared and characterized through content analysis of Pt,MS,IR.The results show that the complex has cis configuration and the bond type of Pt and SCN-is Pt-S.When the aqueous solution of the complex was stored for one week,an orange-yellow precipitation appeared,different from the complex with light yellow color.Further comparative studies of these two complexes suggested that the precipitation is cis-[Pt(NCS)2(NH3)2],the linkage isomerism of cis-[Pt(SCN)2(NH3)2].The mechanism of the isomerism reaction is also discussed.Cis-diaminedithiocyanatoplatinum（Ⅱ） （cis-[Pt （SCN）2 （NH3）2]） was prepared and characterized through content analysis of Pt, MS, IR. The results show that the complex has cis configuration and the bond type of Pt and SCN^- is Pt-S. When the aqueous solution of the complex was stored for one week, an orange-yellow precipitation appeared, different from the complex with light yellow color. Further comparative studies of these two complexes suggested that the precipitation is cis-[Pt（NCS）2（NH3）2], the linkage isomerism of cis-[Pt（SCN）2（NH3）2]. The mechanism of the isomerism reaction is also discussed.
