Spectroscopic Elucidation and Biological Assay of Hybrid Salicylaldehyde-Thiosemicarbazone Nickel & Copper Complexes

Abstract

Thiosemicarbazide Salicylaldehyde legend and their nickel (II) and copper (II) complexes were prepared directly under optimum conditions for 30 minutes. Complexes have been characterized by physicochemical techniques (FT-IR and U.V.). The ligands and their nickel (II) and copper (II) complexes exhibited moderate water solubility. However, they are recorded as appropriate stability in an aqueous solution. I.R. spectrum showed the main functional groups C=N, C=S, N-N, C=C, and legend metal function. Maximum absorption of compounds was measured from 245 to 334 nm. Complexes predict approximately trigonal bipyramidal symmetry. Both the ligand and their complexes established biological evaluation against bacteria and fungi. These results pave the way for using nickel (II) and copper (II) complexes proactive as anti-bacteria and anti-fungi.
