Abstract

Potassium tetrachloroplatinate and asparagine form a paramagnetic complex in aqueous solution. This complex which displays a blue green color has been studied by ESR and IR spectroscopy. The ESR spectra are interpreted to be due to tervalent platinum in a low spin d⁷ configuration. The IR data suggest that the doubly deprotonated ligand is coordinated through the COO^-and CONH^- groups.
