Tridentate Schiff base, Metal complexes, Cytotoxic study, XRD, Antimicrobial study


The Schiff base 4-chloro-N'-[(E)-(2-hydroxy-4-methoxyphenyl)methylidene]benzohydrazide (HCBHV), was prepared by using 2-Hydroxy-4-methoxybenzaldehyde (vanillin) and 4-chlorobenzohydrazide then the solid complexes of Fe(II), Cu(II), Pd(II), Co(II), Mn(II), Ni(II), Zn(II), Hg(II) and Cd(II) were produced. Molar conductivity, magnetic susceptibility, X-ray diffraction, Fourier transform infrared, nuclear magnetic resonance, ultraviolet-visible, and mass spectrometry were all used to characterize these metal complexes. The metal: ligand ratio in these metal complexes was found to be 1:2 by analysis. The physicochemical investigation provides evidence for the presence of square planar geometry around Cu(II), Pd(II), tetrahedral geometry for Cd(II), Hg(II), Zn(II), and octahedral geometry around Mn(II), Co(II), Fe(II), and Ni(II) ions. The IR spectrum data shows that the ligand acts as a tridentate with an OON-donor atom sequence towards the center metal ion. Metal complexes are likely non-electrolytes because of their low molar conductance values. X-ray diffraction analysis indicates that these compounds likely adopt a monoclinic crystal structure. S. aureus MCC 2408, B. subtilis MCC 2010, P. aeruginosa MCC 2080, and E. coli MCC 2412 were used as test organisms for the HCBHV ligand and their metal complexes' antibacterial and fungicidal activities, respectively
