| Abstract | ||
| ABSTRACT This research includes the synthesis and characterization of Shiff's bases crown ethers prepared from condensation between cis-diaminodibenzo-18-crown-6 and benzaldehyde substituted with some groups such as; 4-H , 4-CH2(CH2)6CH3 , 4-Cl , 4-Br and 4-NO2 and their complexes with Fe(NO3)3.9H2O .The study involved solubility, melting points and thermal stability, elemental analysis have been detected with spectral studies using 1H-NMR, UV-Visible and IR-spectroscopy .They found to be solid crystalline and appear to be salt Shiff's bases crown ethers formed by Ion-dipole interaction between the cation and the negatively charged oxygen atoms symmetrically placed in the crown ether ring .The complexes were prepared with molar ratio 1:1(ligand:metal salt) .they were found to have the general formula :- [Fe (L) (NO3)3.9H2O]. Keywords: Crown ethers, Schiff's bases, Crown ethers complexes. | ||
