FIELD: chemistry of metalloorganic compounds, chemical technology.
SUBSTANCE: invention relates to a method for synthesis of salts potassium or ammonium trichloroammine platinum (II). Method involves interaction of cis-dichlorodiammine platinum (II) in solution with hydrochloric acid at heating and addition of [Pt(NH3)4]Cl2 x H2O and isolation of [Pt(NH3)4] x [Pt(NH3)Cl3]2 salt. [Pt(NH3)4] x [Pt(NH3)Cl3]2 salt is dissolved in hot solution of salts M2[PtCl4] wherein M means NH4 +, K+ in hydrochloric acid at heating, [Pt(NH3)4] x [PtCl4] salt is isolated and crystallization of final substances M[PtNH3Cl3] x H2O wherein M means NH4 +, K+ is carried out from hydrochloric acid solutions. Distinction of the claimed method involves the concentration of cis-dichlorodiammine platinum (II) salt must be 0.14 mole/l, not above, the concentration of hydrochloric acid - 6 mole/l, the reaction time carrying out at heating - 3 h, not above. Interaction of [Pt(NH3)4] x [Pt(NH3)Cl3]2 with hot solution of salts Mw[PtCl4] wherein M means NH4 +, K+ in 1M hydrochloric acid is carried out for 30 min at heating and [Pt(NH3)4] x [PtCl4] is isolated. Crystallization of final substances M[PtNH3Cl3] x H2O wherein M means NH4 +, K+ is carried out from hydrochloric acid solution taken in the concentration 6.5-10.6 mole/l at room temperature. Indicated distinctions provide enhancing the yield of the final substance and reducing the content of impurities.
EFFECT: improved method of synthesis.
