Homo Cu(II) and Co(II) binuclear complexes H[MLClMCl 2 ] formed by using the donor properties of the cis two oxygen atoms of the tridentate N ‐(2‐carboxyphenyl)‐salicylaldimine Schiff base derived from salicylaldehyde and anthranilic acid have been synthesized. It was found that the Cu(II) “complexed ligand” readily reacts with CoCl 2 to form mononuclear Co(II) and binuclear oxygen bridged Co(II) complex [Co 2 ‐L 2 ](H 2 O) 2 . The structure of the so prepared complexes was investigated using microchemical analysis, molar conductance measurements as well as electronic and vibrational spectral studies. It was concluded that in the Cu(II) binuclear complex, the Cu(II) ion inside the “complexed ligand” has a planar structure while the other Cu(II) ion is distorted away from planarity. In the Co(II) binuclear complex, the Co atom of the “complexed ligand” is distorted from tetrahedral structure when it coordinates to the second Co atom.
