(a) PMR spectra in the region of CH2 protons recorded in D2O for -AlaH; (b) PMR spectra in the region of CH2 protons recorded in acetone-d6 for trans-[Pt(-AlaH)2Cl2]; (c) PMR spectra in the region of CH2 protons recorded in acetone-d6 with NH2 proton coupling suppression for trans-[Pt(-AlaH)2Cl2]; (d) PMR spectra in the region of CH2 protons recorded in D2O for cis-[Pt(-Ala)2]. X: broadened signal of the H2O admixture in acetone (spectra b and c); V: DMSO reference in D2O (spectrume d); : broadened doublet of splitting at 195Pt (spectrume d).
