A chain of metal(II) chelates that M = Co2+, Ni2+, and Cu2+ have been produced from 2‐(4‐sulfadiazine)hydrazono dimedone (HL) and characterized on analyses of elemental, Fourier‐transform infrared (FTIR) spectra, electronic, susceptibility to magnetic fields, and molar conductance. The chelates are nonelectrolytes, according to measurements of conductance. Spectroscopy methods and additional analytical measurements detect pseudo octahedral shape of Co2+ and Ni2+ chelates, but square planar structure for Cu2+ chelate. The ligand (HL) acts as a monobasic bidentate ligand by coordinating via oxygen atom of the carbonyl (C═O) group and the nitrogen atom of the hydrazone moiety (NH) with deprotonation. The enhanced, bond angles, bond lengths, and quantum chemical factors were used to determine the ligand and its complexes. Absorption spectra method and measurements of viscosity were used to investigate DNA linking activity. In the viability experiment of vinblastine and colchicine, the findings of synthesized compounds against the human cancer cell lines MCF‐7 and HepG‐2 were reported in contrast to positive controls. The antioxidant function of chelates is resolute by means of the free radical‐scavenging analyze (DPPH). As a final point, the antimicrobial effects of the chelates were studied utilizing the diffusion disc technique on fungal (Candida albicans), gram‐positive (Staphylococcus aureus), and gram‐negative (Escherichia coli) bacteria.
