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.

“…Antimicrobial activity: Qualitative determination of antimicrobial activities of the compounds was done using the disk diffusion method. [18,19] The results are summarized in Table 5. Compound (1) showed weak activities against Escherichia coli, Staphyloccocus aureus, and Bacillus magaterium, and no activity against Bacillus subtilis.…”

Abstract). The complexes have been characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction. The L 1 ligand coordinates to the Co atom through the phenolate O and carbonyl O atoms, while the L 2 ligand coordinates to the Co atom through the phenolate O and imino N atoms. The Co atom in complex 1 adopts octahedral coordination and that in complex 2 adopts tetrahedral coordination. The effect of the free ligands and the cobalt complexes on the antimicrobial activities against Staphylococcus aureus, Escherichia coli, and Candida albicans was studied.
