Özet

In this study, the crystal structures of the dispiroansa spermine derivatives of cyclotriphosphazene are characterised for the first time. The reaction of spiro-, gem-disubstituted cyclotriphosphazene derivatives, N3P3Cl4R2 [R = NHPh, (HN(CH2)(3)NH)(0.5), (OCH2C(CH3)(2)CH2O)(0.5)], (1-3), with spermine (4), in aprotic solvents such as CH2Cl2 results in a series of dispirobino spermine derivatives of cyclotriphosphazene (5a, 6a, 7), namely spermine bridged compounds. Whereas, in protic solvents such as CHCl3 give, dispiroansa derivatives (8-10) namely tetracyclic cyclotriphosphazene. The new series of dispirobino and dispiroansa spermine derivatives of cyclotriphosphazene (5a, 6a, 7-10) have been characterised by elemental analysis, mass spectrometry, X-ray (for 5a, 8,10) and H-1, P-31 NMR spectroscopies.
