Synthesis of Ammonium Trichloromonoammineplatinate(II) Improved through Control of Temperature.

Abstract

In the reaction of cis-{[}PtCl2(NH3)2] with HCl, the impact of temperature on the progress of the reaction was found to be critical, and an unexpected temperature effect was discovered. As a result of these findings the side reactions could be avoided, and the reaction between cis-{[}PtCl2(NH3)2] and HCl could be carried on to completion, with production solely of NH4{[}PtC]3NH3]. The crystal structure of NH4{[}PtC]3NH3].H2O is described.
