A series of metal (II) complexes of N‐cyclohexyl amine dithiocarbamate ligand are synthesized and characterized by Fourier transform infrared, 1H, 13C NMR, mass spectroscopy, and elemental analysis. The surface structural pattern of the prepared complexes were investigated by scanning electron microscope and X‐ray diffraction techniques. The prepared complexes possessed crystalline characteristic with size average ranging from 16 to 30 nm. Moreover, the biological activity of the synthesized complexes were tested against Klebsiella pneumoniae, Escherichia coli, and Staphylococcus aureus. Among the prepared complexes, copper (II) complex displayed the highest activity. In addition, molecular docking study was performed against bacterial tyrosinase enzyme which showed good binding interactions and is in agreement with the experimental findings. Furthermore, the in silico toxicity studies reveal that the complexes are mostly non‐irritant with mild toxicity. Different quantum parameters including electron affinity, ionization energy, dipole moment, hardness and vibrational frequencies were calculated for the ligand and its complexes using Gaussian 09 program and B3LYP/SDD level of theory.
