Glycolatoplatinum (II) complexes,[Pt (OCOCH 2 O) L 2], having a novel five-membered ring structure were obtained by adding an equimolar quantity of glycolic acid to cis-[Pt (OH) 2 L 2](L: NH 3, amines) in water followed by heating. These complexes have also been obtained by reaction of cis-[Pt (NO 3) 2 L 2] with sodium glycolate in neutral aqueous solution. These complexes have been characterized by SIMS, IR, and NMR spectroscopy.
