Abstract
A novel six-coordinate complex of Zr(IV) with curcumin ligand was synthesized and characterized by thermogravimetric analysis, elemental analysis and spectroscopic techniques. 1HNMR and 13CNMR spectra showed that two curcumin ligands behave as a bidentate monobasic ligand and occupy trans- positions, while two other remaining coordination sites of zirconium are occupied by O and H2O. The complex was screened for antibacterial activity and showed no inhibitory effect against Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Salmonella enteritidis. Eventually it was found that the complex can be used as a non-toxic, stable and exotic orange dye in coloration of cotton fibers.
