The variations in bond lengths (1.1, 1.2, and 1.5 Å) within the pyran ring further contribute to the ligand's stability by maintaining an optimal balance between localized and delocalized bonding interactions. The shorter bonds, indicative of double bond character, and the intermediate bonds, signifying partial double bond character, provide resonance stabilization, while the single bonds maintain structural flexibility. This alternating pattern of bond lengths ensures that the ligand remains chemically robust, resisting cleavage or rearrangement under varying environmental conditions . Moreover, the synergistic interplay between the azomethine group and the Pyran ring enhances the ligand's ability to chelate metal ions, further bolstering its thermodynamic and kinetic stability in coordination complexes. These features make Schiff base ligands ideal for catalytic and electrocatalytic applications where structural integrity is paramount.
