Ligand formation in this research was accomplished by reacting each diazonium salt of 2-aminobenzothiazole with 4-nitroaniline. The ligand was characterized using various spectral techniques, including UV-Vis, FTIR, 1H, and 13CNMR, as well as LC-Mass. Furthermore, micro-elemental analysis (C.H.N.S.O) was conducted. Mn (II), Fe (II), Cd (II), and Hg (II) complexes were synthesized and thoroughly analyzed. The differentiation of metals in the chelates was determined through atomic absorption from flame, element analysis, infrared and UV-Vis spectral methods, and conductibility measurements to investigate their magnetic properties. The study provided insights into the molar ratio and continuous variation methods used to identify the compounds. Beer's law was utilized to determine the absorbance range (1×10-4 - 3×10-4 M/L), and complex solutions with high absorbability were observed. Analytical data for each chelated metal was reported in a 1:2 ratio of metallic ligand. The compounds displayed an octahedral geometry, as indicated by physico-chemical reference. Additionally, the biological activity of the compounds was evaluated. Moreover, for the practicality of these complexes, the Mn-complex was studied in the epoxidation of substituted styrene compounds as the target alkene to produce epoxide products.
