Abstract

Platinum complex of the type [L1L2Pt[O(CO)R1]X]n, wherein L1 and L2 are the same or different monoolefin ligands or together represent a compound L1L2 acting as a diolefin ligand, wherein X is selected from bromide, chloride, iodide, and —O(CO)R2, wherein —O(CO)R1 and —O(CO)R2 are the same or different C6-C18 or C8-C18 non-aromatic monocarboxylic acid groups with the exception of a phenylacetic acid group, or together represent a C8-C18 non-aromatic dicarboxylic acid group —O(CO)R1R2(CO)O—, wherein it is a mononuclear platinum complex where n=1, or wherein, in the event of the presence of L1L2 and/or of —O(CO)R1R2(CO)O—, it may be a polynuclear platinum complex with a whole number n>1.
