Dithiocarbamate is a ligand that can act as a corrosion inhibitor due to the presence of sulphur and nitrogen atoms. Ni(II) N-methylcyclohexyl dithiocarbamate, Ni[MeCycHexdtc]2 and Ni(II) N-ethylcyclohexyldithiocarbamate, Ni[EtCycHexdtc]2 complexes were synthesized through direct synthetic method at room temperature and characterized using the Elemental Analyzer (CHNS), Fourier Transform Infrared-Attenuated Total Reflectance (FTIR-ATR), Ultraviolet-Visible (UV-Vis), Nuclear Magnetic Resonance (NMR), molar conductivity, and gravimetric analysis. The Ni[MeCycHexdtc]2 complex had indicated a square planar geometry, but it was not the case for the Ni[EtCycHexdtc]2 complex which showed a tetrahedral geometry. The efficiency of the synthesized inhibitors was studied in different concentrations; 0.001 M, 0.01 M, and 0.1 M (1 M HCl and 1 M H2SO4) at room temperature.
