Abstract: | Complexes of Pd(II) with aminobutyric acid AmH = NH2CH(CH2CH3)COOH, namely, trans-[Pd(AmH)2Cl2] with monodentate (via the NH2 group) AmH ligands and cis-, trans-Pd(Am)2 with bidentate (via NH2 and COO groups) ligands have been synthesized for the first time. Elemental analysis and IR and NMR spectroscopy were used to identify the synthesized compounds. The NMR spectra of the Pd(II) complexes were interpreted by comparing them with the NMR spectra of the analogous complexes of Pt(II). For Pt(II) and Pd(II) complexes with aminobutyric acid used as examples, an approach to identification of diastereomer bis-aminoacid complexes in specimens with racemic aminoacids by NMR spectroscopy is demonstrated. |
