Crystal structure of complex [Zn(L¹)Cl₂] was determined. In the structure of the complex, each Zn(II) ion is four coordinated binding to phenolate oxygen and imine nitrogen atoms of the ligand L¹ and two chloride atoms in approximately tetrahedral geometry. The equilibrium geometry of three Schiff base ligands (HL¹-HL³) and their Cu(II) and Zn(II) complexes were calculated using the density functional theory (DFT/B3LYP) method with the 6–31++G(d,p) basis set for the C, H, Cl, N, O, P atoms and LANL2DZ for the I atom. Frontier molecular orbitals (HOMO, LUMO) analyses were conducted for the optimized geometries of the compounds, and chemical reactivity descriptors such as hardness, softness, electrophilicity, and electronegativity were examined. Additionally, the molecular electrostatic potential (MEP) of all compounds was modeled using DFT calculations. These calculations were thoroughly examined, and their implications were discussed. The ligands and their metal complexes were investigated for their DNA binding properties. The compounds showed comparable DNA binding properties to ethidium bromide (EB) and 5-fluorouracyl (5-Fu) with DNA binding constant (<em>K</em>_b) 1.5–6.25 × 10⁵ M⁻¹.

It should be noted that these electronic rearrangements imply a very high energy barrier in the ground state, where [2 + 2] cycloaddition is forbidden by the orbital symmetry rules. A crucial bonding process that leads to C<img>C bond formation in both the ground and excited states is the presence of non-bonding centers.
