New complexes of 2,3-bis(5-(4-chlorophenyl)diazenyl)-2-hydroxybenzylideneamino)maleonitrile (CDHBDMN) with VO(II), Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) were synthesized and characterized by analytical and physicochemical techniques, that is, elemental analyses, molar conductivity, UV, IR, EPR, 1 H-NMR spectra, magnetic susceptibility and also by aid of scanning electron microscopy (SEM), nonlinear optical study (NLO), �uorescence spectral studies, and solvatochromic behaviors. Electronic and magnetic susceptibility measurements of the complexes indicate square pyramidal geometry for VO(II), octahedral for Ni(II), and square planar geometry for all the other complexes. e EPR spectral data provide information about their structures on the basis of Hamiltonian parameters and the degree of covalency. ese metal complexes were also tested for their antibacterial and antifungal activities to assess their inhibiting potential. Metal-mediated �uorescence enhancement is observed on complexation of the azo Schiff base ligand. e synthesized compounds were investigated for nonlinear optical properties, and the surface morphology of the Cu(II) complex was studied by scanning electron microscopy.

“…Zinc is an element of the fifth period of the periodic table whose d orbital is filled, i.e., a d 10 metal. The complexes formed with a zinc atom at their metallic center may assume three different geometries: trigonal, octahedral, and tetrahedral, the latter being the most common geometry for zinc complexes described in the literature 13,14 . The second most abundant metal ion in the human body after Fe 2+ , Zn 2+ is considered a biometal as it plays a vital role in regulating metalloenzymes, which act as structural and catalytic cofactors 15 .…”

This article reports the synthesis of seven Zn(II) complexes containing N-acylhydrazone ligands (L1 to L7) and the assessment of their antioxidant. Microwave assisted-synthesis of ligands with ZnCl2 in MeOH yielded tetrahedral Zn(II) complexes with a 1:2 metal: ligand ratio, characterized by HRMS, FTIR, and UV-Vis spectroscopy, thermal and electrochemical analyses, and DFT calculations. The (L3)2Zn complex exhibited the lowest thermal stability, and (L6)2Zn and (L7)2Zn were the most stable. XRD powder showed that all complexes have good crystallinity with crystalline dimensions ranging from 32 to 86 nm. Cyclic voltammetry of Zn(II) complexes indicated a reversible redox process for (L4)2Zn and an irreversible process for the remaining six complexes: (L1)2Zn to (L3)2Zn and (L5)2Zn to (L7)2Zn. Antioxidant activity of ligands and complexes was assessed by the DPPH method; the L7 ligand and corresponding (L7)2Zn complex exhibited good activity, IC50 = 65.30 μmol.l-1 and 78.70 μmol.l-1, respectively, when compared with standard ascorbic acid.
