Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
74 words
A cis co-ordination compound of platinum having the structure ##STR3## in which X and Y are the same or different ligands selected from sulphate, phosphate, nitrate, haloacetate and water or together comprise oxalato, succinato, glutarato, adipato, pimelato, malato or phthalato ligands and A and B are selected from the group consisting of isopropylamine, isobutylamine and isopentylamine coordinated to the Pt through their N atoms, such that the platinum is present as Pt 2+ .
Claim 2
Dependent Claim
74 words
A cis co-ordination compound of platinum having the structure ##STR3## in which X and Y are the same or different ligands selected from sulphate, phosphate, nitrate, haloacetate and water or together comprise oxalato, succinato, glutarato, adipato, pimelato, malato or phthalato ligands and A and B are selected from the group consisting of isopropylamine, isobutylamine and isopentylamine coordinated to the Pt through their N atoms, such that the platinum is present as Pt 2+ .
