The ditopic ligand 3 has been synthesized. In its crystallography. Magnetic studies of complex 1 indicate a very weak antiferromagnetic coupling between the deprotonated form, it reacts with copper (II) ions to form a tetranuclear complex 1 of the [2× 2] CuII 4 grid type, the phenoxo-bridged CuII ions. structure of which has been confirmed by X-ray
