Platinum Blues - a Study of the Interaction between Potassium Tetrachloroplatinate and Asparagine

Abstract

<jats:title>Abstract</jats:title><jats:p> 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 d<jats:sup>7</jats:sup> configuration. The IR data suggest that the doubly deprotonated ligand is coordinated through the COO<jats:sup>- </jats:sup>and CONH<jats:sup>-</jats:sup> groups.</jats:p>
