SYNTHESIS OF (GLYCOLATO-O,O′)DIAMMINEPLATINUM(II) AND ITS RELATED COMPLEXES

Glycolatoplatinum(II) complexes, [Pt(OCOCH2O)L2], having a novel five-membered ring structure were obtained by adding an equimolar quantity of glycolic acid to cis-[Pt(OH)2L2] (L: NH3, amines) in water followed by heating. These complexes have also been obtained by reaction of cis-[Pt(NO3)2L2] with sodium glycolate in neutral aqueous solution. These complexes have been characterized by SIMS, IR, and NMR spectroscopy.
