摘要：

The interaction of the clathrate Pt6Cl12 . 0.1 EtCl . 5.7H2O with RCN nitriles results in cis-[Pt(PhCH2CN)2Cl2] and in [Pt(RCN)2Cl2] (R = CH2CO2Et, Ph) complexes as a mixture of cis- and trans-isomers which separated and characterized. Cis[ Pt(MeCN)2Cl2] has been synthesized using a well known technique of K2[PtCl4] interaction with acetonitrile in water. Heating cis-[Pt(RCN)2Cl2] (R = Me, CH2Ph, CH2CO2Et) in the solid phase leads to cis-trans isomerization. In case of cis-[Pt(PhCN)2Cl2] thermal conversion results in trans-[Pt(PhCN)2Cl2] but the process of geometrical isomerizations accompained by a considerable decomposition of starting material and/or final products. Boiling of cis-[Pt(PhCH2CN)2Cl2] in mixture of EtNO2-PhCH2CN or cis-[Pt(EtCO2CH2CN)2Cl2] in MeNO2 or EtNO2 solutions results in complete cis-trans conversion. Similarily heating of cis-[Pt(RCN)2Cl2] (R = Me, Ph) in solution produces an equilibrium mixture of cis- and trans-isomers
