Abstract:
In this study, aldehydes were prepared by reaction of potassium salt of salicylaldehydewith dibromoalkane derivatives or tosilat esters of diol. Then, Macrocyclic Schiff bases[1,3,5-Triaza-2,4:7,8:13,14-tribenzo-9,12-dioksa-siklopentadeca-1,5-dien(L1), 1,3,5-Triaza-2,4:7,8:,14,15-tribenzo-9,13-dioksasiklohekxadeca-1,5-dien(L2), 1,3,5-Triaza-2,4:7,8:15,16-tribenzo-9,15-dioksasiklo-heptadeca-1,5-dien(L3), 1,3,5-Triaza-2,4:7,8:16,17-tribenzo-9,12,15-trioksasiklooctadeca-1,5-dien(L4), 1,3,5-Triaza-2,4:7,8:19,20-tribenzo-9,12,15,18-tetraoksasiklouncosa-1,5-dien(L5)] were synthesized by reaction of 2,6-diaminopyridine and1,2-Bis(2-carboxyaldehyde fenoxy)ethane, 1,3-Bis(2-carboxyaldehyde fenoxy)propane, 1,4-Bis(2-carboxyaldehyde fenoxy)butane, 1,7-Bis(2-formylphenyl)-1,4,7-trioksaheptane, 1,10-Bis(2-formylphenyl)-1,4,7,10-trioksadecane in methanol respectively. Then, metal complexeswere synthesized from 2,6-diaminopyridine with 1,2-Bis(2-carboxyaldehyde fenoxy)ethane,1,3-Bis(2-carboxyaldehyde fenoxy)propane, 1,4-Bis(2-carboxyaldehyde fenoxy)butane, 1,7-Bis(2-formylphenyl)-1,4,7-trioksaheptane, 1,10-Bis(2-formylphenyl)-1,4,7,10-trioksadecaneand Pb(NO3)2, Cu(NO3)2.3H2O, Ni(NO3)2.6H2O, Co(NO3)2.6H2O, La(NO3)3.6H2O inmethanol with template effect respectively. The structure of the ligands and their complexeswere characterized by Elemental Analyses, Magnetic Susseptibility, FTIR, UV-Vis,Conductance Measurements, 1H-NMR and 13C-NMR spectra, Mass Spectra and TGA.Key words: 2,6-diaminopyridine, Macrocyclic Schiff bases, Macrocyclic Schiff BaseComplexes, Aromatic Aldehydes.
