FIELD: chemistry.
SUBSTANCE: invention pertains to the method of obtaining platinum (II) compounds, and specifically to pyrophosphate tetrammine di-platinum (II), which can be used as an intermediate compound during synthesis of cis-dichlorodiammineplatinum (II). The method involves adding sodium pyrophosphate to a solution of potassium tetrachloroplatinate (II) in a medium of ammonium acetate and heating the mixture for 1 hour on a water bath at pH=5, with subsequent addition of a second portion of sodium pyrophosphate and heating the solution for 4 hours. The released salt of pyrophosphate tetrammine diplatinum (II) is washed in water and spirit and dried at room temperature.
EFFECT: high degree of purity of the compound.
