“…The spectra of the complexes of the type [M( κ 2 ‐Saly) 2 ] are displayed within 1593–1600 cm − 1 range, due to the ν(C═N) group; this band is shifted toward lower frequency than the free ligand (1623 cm −1 ), indicating the (C═N) group participates in the bonding with the metal ions 36–38 ; also, the spectra displayed the disappearance of a phenolic OH group (which appeared at 3394 cm −1 in free ligand). The deprotonation of a phenolic OH group and shift of the ν(C═N) frequency indicate the formation of the chelate ring through the oxygen atom of phenolate group and nitrogen atom of oxyiminohydroxyl group.…”

“…[5,7,9,41] The fourth characteristic band observed within 1016-1039 cm À1 range is due to the υ(N-O) mode; this band was shifted to higher energy of 23-46 cm À1 , indicating bonding of the Saly À ligand through the oxyimino nitrogen. [35][36][37] The IR spectra displayed a medium to weak intensity band within 416-443 and 459-503 cm À1 range, which is assigned to the υ(M-N) and υ(M-O) modes, respectively. [38][39][40] The electronic spectra of the salicylaldoxime ligand displayed three bands at 226, 262, and 311 nm assigned to the π !…”

New nanophenolic oxime complexes of the type [M(κ 2 -Saly) 2 ] {where HSaly = salicyl-aldoxime; M = Co(1), Ni(2), Cu(3), Pd(4), Pt(5), Zn(6), Cd(7), and Hg(8)} were prepared and characterized by different spectroscopic methods. The surface morphology and the micrographs of the investigated complexes were checked by the scanning electron microscopy (SEM) and Xray diffraction (XRD) analysis. The results indicate the successful preparation of nanocomplexes with nanoparticles size. In addition, the antibacterial activity was studied against three different pathogenic bacteria, and the Pt(II) complex displayed the highest activity compared with free salicylaldoxime ligand and other complexes. Magnetic susceptibility and ultraviolet (UV)-visible spectroscopic measurements were used to deduce the geometry of the complexes, which was then validated by density functional theory (DFT) calculations. The in vitro antitumor activity was investigated by MTT assays against HepG-2 cell lines. The Zn(II) and Pt(II) complexes displayed good activity with IC 50 values at 17.31 ± 0.95 and 11.78 ± 0.54 μM, respectively. In contrast, the [Cu(Saly) 2 ] and [Ni(Saly) 2 ] complexes showed the lowest activity against tested cells.

Reaction of metal saltsCoCl 2 •6H 2 O,NiCl 2 •6H 2 O and Na 2 [PdCl 4 ] with thymine bisdithiocarbamate and uracil bisthiocarbamate in molar ratio 2:1 (metal/ligand) affords the presumably tetrahedral complexes [M 2 (dtc)(H 2 O) 4 Cl 2 ] M; Co, Ni and square planer complexes [Pd(dtc)(H 2 O) 4 Cl 2 ] dtc=tdtc, utdc. Dithiocarbamates (dtcs) behave as monodentate ligands. Reaction of [M 2 dtc (H 2 O) 4 Cl 2 ] M; Co (II), Ni (II), and Pd(II) with 1,10-Phen.″ or 2,2′-BiPy. (two equivalents) affords tetrahedral complexes of type [M 2 dtc(Amin) 2 Cl 2 ] M; Co, Ni and square planer complexes [Pd 2 dtc(Amin) 2 Cl 2 ], bis(dithiocarbametes) acts as a monodentate ligand and binds to the metal center through the soft sulfur atoms. Antibacterial activity of ligands and complexes is evaluated with two types of bacteria Staphylococcus aurous (gram-positive) and Escherichia coli (gram-negative). The complexes are characterized by physico-chemical and spectroscopic methods.

Seven Zn-dithiocarbamate complexes were suggested as corrosion inhibitors. Density functional theory (DFT) was used to predict the ability of inhibition. Room temperature conditions were applied to suggest the optimization of complexes, physical properties, and corrosion parameters. In addition, the HOMO, LUMO, dipole moment, energy gap, and other parameters were used to compare the inhibitors efficiency. Gaussian 09 software with LanL2DZ basis set was used. Total electron density (TED) and electrostatic surface potential (ESP) were utilized to show the sites of adsorption according to electron density.
