Abstract In the present work, a pyrazole derivative ligand HDMP (3-(3,5-dimethylpyrazol-1-yl)-3-oxopropionitrile) besides its Cu(II), Hg(II) & Mn(II) complexes are prepared. On the view of structure characterization, various spectroscopic analyses are applied (IR, UV–Visible, 1HNMR and EPR). Also, Cu(II) complex is selected to undergo different X-ray techniques including (SEM, TEM and powder XRD) to predict the surface morphology, the size of particle and the extent of complex crystallinity. Additionally, molecular electrostatic potential molecular, modeling of the geometric optimized compounds, highest occupied and lowest unoccupied molecular orbitals are performed using DMOL3 based on DFT method. The cyclic voltammetry of Cu(II) in (absence/ presence) of HDMP were studied to investigate the effect of complex formation on the electrochemical manners of Cu(II) ion. Finally, biological investigation involving (Anti-microbial, Anti-oxidant activity and Bleomycin-dependent DNA damage) are screened.
