摘要:
Multifunctional cyclophosphazene ligands with 2-, 3-, and 4-pyridylalkylamino- or 4-pyridylmethoxy groups, N3P3(OC6H5)(5)(NHCH2(C5H4N-2)) (1), N3P3(OC6H5)5 .(NHCH2(C5H4N-3)) (2), N3P3(OC6H5)(5)(NHCH2(C5H4N-4)) (3) and N3P3(OC6H5)(5)(OCH2(C5H4N-4)) (4) are accessible through reactions of monochlorpentaphenoxycyclotriphosphaza-1,3,5-trien with aminomethylpyridine or pyridyl methanolate. 1 does not react with mercury(II) iodide whereas 2-4 yield the metal complexes 2 a, 3 a, and 4 a by interactions of the pyridyl nitrogen atoms. The X-ray single crystal structure analyses of these compounds shows that 2a and 4a are dimers, whereas 3a is a HgI2 polymer with syndiotacticaly al-ranged ligands.
