ABSTRACT

The present study deals with the structure and antimicrobial properties of some complexes of Co(II), Ni(II), Cu(II), Zn(II)   with a new Mannich base (1-(3-furan-2-yl)-3-oxo-1-phenyl propyl) semicarbazide (FBSC). The ligand and the complexes have been characterized by various physico-chemical techniques such as elemental analysis, molar conductance, magnetic susceptibility measurements, infrared and electronic spectra.  Based on these data, we propose tetrahedral geometry for Co(II) and Zn(II), square planar geometry for Ni(II) and octahedral geometry for Cu(II) complexes.  Antibacterial activities of the ligand and its complexes were tested against some selected bacteria.

Key words: Mannich base, Semicarbazide, Spectral Studies, Geometry, Antibacterial Activity.
