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.

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. Different from the complex with light yellow color. Future comparative studies of these two complexes suggest that the precipitation is cis - [Pt (NCS) 2 (NH3) 2], the linkage isomerism of cis- [Pt (SCN) 2 (NH3) 2].
