The ligand reacts with Co(II), Ni(II) and Cu(II) salts to form complexes. The ligand has been characterized by FTIR, 1 H NMR (DMSO-d 6), UV-vis and mass spectra, elemental analysis and fluorescence spectrophotometry. Protonation constants of the ligand and overall formation constants of the complexes have been calculated from potentiometric data using a computer program. IPC Code: Int. Cl. 8 C07F1/08; C07F15/04; C07F15/06 The coordination chemistry of Schiff bases derived from the reaction of salicylaldehyde and o-diamines has been the subject of many studies and a number of them are used as oxygen carriess to mimic compli-cated biological systems 1-7 . They are also efficient reagents in trace analysis of some metal cations 8 . Schiff ...
