Preparation and Spectroscopic Characterization of Iron(III) Complexes of a Functionalized Crown Ether
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)6CH 3 , 4-Cl , 4-Br and 4-NO2 and their complexes with Fe(NOO.The stud...

| Summary: | 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)6CH 3 , 4-Cl , 4-Br and 4-NO2 and their complexes with Fe(NOO.The study involved solubility, melting points and thermal stability, elemental analysis have been detected with spectral studies using 1 H-NMR, UV-Visible and IR-spectroscopy .Theyfound to be solid crystalline and appear to be salt Shiff's bases crown ethers formed by Iondipole 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 :-
