Zn(II), Cd(II), and Hg(II) dithiocarbamate complexes were synthesize and characterized by elemental analysis, thermogravimetric analysis, UV-Vis, FTIR, and1H- and13C-NMR spectroscopy. Single-crystal X-ray crystallography revealed that the Zn complex has a centrosymmetric dimeric structure while the Hg complex crystallizes with two monomeric molecules of the mercury complex and two molecules of toluene solvent in the asymmetric unit. The compounds were used as single molecule precursors to synthesize HDA capped metal sulfides nanoparticles with average crystallite size ranging from 7 to 22 nm. The optical properties of the nanoparticles showed evidence of quantum confinement.

Inhibition of C38 carbon steel corrosion by 4-methyl-3-phenyl-2(3H)-thiazolethione (TO1) and 4-methyl-2-(methylthio)-3- phenylthiazol-3-ium (ST1) in 1 ?M HCl was investigated by weight loss and electrochemical methods. All of the data obtained reveal that the two compounds act as good inhibitors in this media. At optimized concentration TO1 and ST1 showed the highest inhibition efficiency of 98.8% (2.10?4 ?M) and 93.86% (10?3 ?M) respectively. Polarization curves show that inhibitor molecules act as mixed type inhibitors. The impedance study showed that an increase in the concentration of the two inhibitors is accompanied by an increase in polarization resistance and a decrease in double layer capacitance. The Langmuir isotherm very well describes the adsorption of inhibitors to the surface of the corroding metal and the thermodynamic parameters showed that the adsorption of the two compounds was strong and chemical nature. X-ray photoelectron spectroscopy (XPS) confirms and describes the absorption of inhibitors under investigation on the metal surface.

Dithiocarbamate ligands obtained from primary amines, namely N-phenylaniline, 4-methylaniline and 4-ethylaniline, and represented as L1, L2 and L3 respectively, have been used to prepare some Ni(II), Pd(II) and Pt(II) complexes. The complexes were characterized by NMR, FTIR spectroscopy and elemental analysis. The spectroscopic data showed that the ligands were chelated to the metal ions in a bidentate mode. The complexes [Pt(L1)2], [Pt(L3)2], and [Pd(L1)2] were further characterized by single crystal X-ray analysis and distorted square planar geometries were confirmed in all cases. The magnetic susceptibility measurements of the nickel complexes suggest a square planar geometry for the diamagnetic compounds. Thermal decomposition studies of the complexes gave their respective metal sulfides as residues. Geometry optimization and harmonic frequency calculations of the ligands and the complexes were carried out using density functional theory (DFT). Molecular electrostatic potential energy calculations were used to support the coordination through the dithio-sulfur groups of the three dithiocarbamate ligands. Non-covalent interaction (NCI) theory analysis was used to reveal the different intra and intermolecular interactions in the hydrogen bonded structures of the platinum and palladium complexes. Antimicrobial screening, conducted using selected microbes, showed that the complexes gave moderate to very active antimicrobial activities against Gram negative (Escherichia coli, Klebsiella pneumonia and Pseudomonas aeruginosa), Gram positive (Bacillus cereus and Staphylococcus aureus) and fungi (Candida albicans and Aspergillus flavus) organisms at a concentration of at 50 μg/mL. However, the [Pt(L3)2] complex gave the best antimicrobial properties with an inhibitory zone range of 8–26 mm.
