Spectroscopic techniques and single crystal X-ray crystallography confirmed its (─C─NH) tautomeric form and monoclinic structure with a P21/n space group. Centrosymmetric dimers stabilized by C─H⋯O and O─H⋯O hydrogen bonds formed a 3D supramolecular architecture. Hirshfeld surface analysis identified H⋯H and H⋯O/O⋯H interactions as key contributors to crystal packing, emphasizing hydrogen bonding and van der Waals forces. The ligand showed strong DNA-binding affinity, primarily through groove binding, as evidenced by hypochromic shifts in UV–vis spectroscopy upon interaction with CT-DNA. Competitive binding experiments with groove binders DAPI and methyl green confirmed preferential binding to the DNA minor groove. Molecular docking studies supported these findings, revealing the ligand's minor groove binding stabilized by hydrogen bonds, with a calculated binding energy of −8.343 kcal/mol.
