Abstract
A cis co-ordination compound of platinum having the structure ##STR1## in which X and Y are the same or different ligands selected from halide, sulphate, phosphate, nitrate, carboxylate, carboxylate substituted with halogen and water and A and B are the same or different straight-chain alkyl amines containing at least 3 carbon atoms in the alkyl chain co-ordinated to the Pt through their N atoms, such that the platinum is present as Pt.sup.2+.
Claims4
A cis-coordination compound of platinum having the structure:
- ##STR3## in which X and Y are the same or different ligands selected from sulphate, phosphate, nitrate, oxalate, halogen-substituted acetate and water or together form a dicarboxylate ligand selected from the group consisting of succinato, glutarato, adipato, pimelato, malato and phthalato ligands and A and B are the same or different straight-chain aliphatic amines selected from the group consisting of n-propylamine, n-butylamine and n-pentylamine coordinated to the Pt through their N atoms, such that the platinum is present as Pt.sup.2+.
