摘要:
The interaction of platinum(II) nitrile complexes with polydentate ligands, pentaphenoxy(2-pyridylmethylamino) cyclotriphosphazene (L-1), pentaphenoxy( 3-pyridylmethylamino) cyclotriphosphazene (L-2), pentaphenoxy[2-(2- pyridyl) ethylamino] cyclotriphosphazene (L-3), and pentaphenoxy(2-pyridylmethoxy)cyclotriphosphazene (L-4), was studied. The synthesized complexes were characterized by single-crystal X-ray diffraction, H-1 and P-31 NMR spectroscopy, IR spectroscopy, FAB mass spectrometry, and other methods. In complexation of phosphazenes L-1 L-3 with Pt(II) ions, nitrogen atoms of the pyridine ring and alkylamine fragment participate in the coordination to form chelate rings. In the complex with L-4, the substituted phosphazene is coordinated via nitrogen atoms of the pyridyl group and cyclotriphosphazene ring to form a seven-membered ring.
