Compositions containing platinum

Abstract

This invention relates to a compound of platinum having the structure: ##STR1## in which X and Y are halogenoid groups which are the same or different and are preferably both chloride but may be other halide or pseudohalide such as cyanate, thiocyanate and azide or other similar groups, and A and B are the same or different branched chain aliphatic amine groups co-ordinated to the Pt through their N atoms.

What is claimed is: 
     
       1. A co-ordination compound of platinum having the structure: ##STR4## in which X and Y are halogen and A and B are the same or different branched chain aliphatic amine groups or C-substituted branched chain aliphatic amine groups co-ordinated to the Pt through their N atoms each having the general formula   C.sub.n R.sub.2n+1 NH.sub.2     in which n may vary from 3 to 9 and in which all of the R groups are the same or different and are selected from the group consisting of hydrogen, alkyl, aryl, alkaryl, aralkyl, halogen, pseudohalogen, hydroxy, carbonyl, formyl, nitro, amido, amino, sulphonic acid, sulphonic acid salt, carboxylic acid and carboxylic acid salt.   
     
     
       2. A compound according to claim 1 in which X and Y are both chlorine and R is hydrogen. 
     
     
       3. A compound according to claim 1 wherein the platinum is present as Pt 4+ . 
     
     
       4. A compound according to claim 1 wherein the R groups are the same or different lower alkyl. 
     
     
       5. A compound according to claim 1 wherein A and B are isopropylamine, isobutylamine, isoamylamine and 2-aminohexane. 
     
     
       6. A composition comprising a co-ordination compound of platinum having the structures: ##STR5## in which X and Y are halogen and A and B are exo 2 amino norbornane. .Iadd. 
     
     
       7.  The compound cis-dichloro-trans-dihydroxybis (isopropylamine) platinum IV hydrate. .Iaddend..Iadd. 8. A compound according to claim 1 wherein X and Y are both chlorine and A and B are both isopropylamine. .Iaddend.
