A range of metal complexes derived from the HBTADH ligand (4-{[(6-chloro-1,3-benzothiazol-2-yl)imino]methyl}benzene-1,4-diol) have been synthesized, and their structural characterization has been conducted, yielding compounds of the type [M(BTADH)2]. Electron spin resonance (ESR), electronic absorption, mass, electromagnetic moments, NMR, infrared, and C, H, N, and S analysis spectroscopy were some of the methods used for characterization. A tetrahedral geometry has been projected for the complexes containing Hg(II), Zn(II), and Cd (II), but a high spin octahedral geometry is anticipated for the other complexes. In contrast, the spectra suggest that the Pd(II) complex will have a square planar shape. Metal complexes in nitrobenzene do not behave like electrolytes because of the compound's low molar conductance values. In addition, this study examined and evaluated the antibacterial activity of all compounds that were synthesised.
