Synthesis, Spectra And Biological Evaluation Studies Of Fe(II), Cd(II), Mn(II), Co(II), Ni(II), Zn(II), Pd(II), Hg(II) And Cu(II) Complexes With 6-Chloro-2-Aminobenzothiazole Derivatives

Abstract

Metal complexes of the type [M(AMBTDH)₂], (M = Fe(II), Cd(II), Mn(II), Co(II), Ni(II), Zn(II), Pd(II), Hg(II) and Cu(II)) of HAMBTDH (4-{[(6-chloro-1,3-benzothiazol-2-yl)imino]methyl}benzene-1,3-diol) ligand, have been synthesized and characterized by elemental analysis, NMR, infrared, electronic absorption, mass, magnetic moments, Xrd, and ESR spectroscopic methods. Based on the spectrum data, a square planar geometry is proposed for the Pd(II) complex; tetrahedral geometry is proposed for the Hg(II), Cd(II), and Zn(II) complexes; and high spin octahedral in nature is proposed for the other complexes. The low molar conductance values in nitrobenzene indicate that the metal complexes are non-electrolytes.  Additionally, the antimicrobial activities of the all-prepared compounds were investigated and analysed as part of this investigation.
