Summary
-
1.
It has been shown that, when equimolecular amounts of K2[PtBr4] and K2[Pt(NO2)4] react, the product has the composition K2[Pt(NO2)2Br2], and behaves like a mixture of geometric isomerides.
-
2.
Treatment of a solution of the salt K2[Pt(NO2)2Br2], obtained as indicated above, with ammonia yields trans-dinitrodiammineplatinum:containing cis-dinitrodiammineplatinum impurity.
-
3.
A new reaction has been applied for the distinguishing of the two isomers of dinitrodiammineplatinum.
