Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
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.
