Schiff base complexes of general formula [M(MDES)²X²] where M = Co(II), Ni(II) and Cu(II), MDES = 1-methyl- 2, 6 diethyl piperidone semicarbazone and X = Cl-, Br-, I- and NO₃-, have been synthesized. The ligand as well as metal complexes were characterized by elemental analyses, IR spectra, electronic spectra, molar conductivity and magnetic susceptibility measurements. On the basis of above observations it has been observed that ligand acts as neutral bidentate manner and coordination proposed through azomethine nitrogen and carbonyl oxygen of semicarbazone moiety. The remaining coordination centres are satisfied by anions such as Cl-, Br-, I- and NO_3-. On the basis of electronic spectral data and magnetic susceptibility data the gometry of the complexes tentatively proposed octahedral. Antibacterial activity of ligand and complexes were also determined.
