| Abstract: | As a multidonor ligand with phenanthroline and salicylaldimine functionalities on the same molecule, 5,6-bis(salicylideneimino)-1,10-phenanthroline (LH2) has been synthesized by the reaction of 5,6-diamino-1,10-phenanthroline with salicylaldehyde and its metal complexes with Ni(II) and Cu(II) have been prepared. Both of the isolated complexes are trinuclear with metal ligand ratio of 3:2. Protonation constants of LH2 which have been determined by potentiometric titration in solution are log K1=8.96, log K2=15. 88, log K3=8.73 and log K4=2.78. The newly synthesized compounds have been verified by IR, 1H NMR and mass spectra together with elemental analysis. |
