Abstract: | Reactions of platinum(II) and platinum(IV) nitrile complexes with polydentate ligands, such as pentaphenoxy(2-pyridylmethylamino)cyclotriphosphazene, pentaphenoxy(3-pyridylmethylamino)cyclotriphosphazene, and pentaphenoxy(2-pyridylethylamino)cyclotriphosphazene, were studied. Platinum(IV) is reduced to platinum(II) upon complex formation; the pyridine and alkylamine nitrogen atoms coordinate to platinum(II) to form chelate rings. The compounds obtained were characterized by 1H and 31P NMR and IR spectroscopy, FAB mass spectrometry, and other methods. |
