ABSTRACT

A new series of aluminium (III) complexes with semicarbazones and thiosemicarbazone in 1:1 (M:L) molar ratio in dry benzene have been synthesized. Ligands used in these studies have been prepared by the condensation of diketones/dialdehydes with thiosemicarbazide and semicarbazide hydrochloride using ethanol as reaction medium. The bonding pattern and structural studies of these coordination compounds have been carried out by elemental analysis, IR and 1H NMR spectral studies. The antibacterial studies of the ligands and their metal complexes have been carried out and their results have been reported.

Keywords: Aluminium (III) complexes, Coordination compounds, Semicarbazone, Thiosemicarbazone, Antimicrobial activities.
