Palladium Complex Containing Curcumin as Ligand: Thermal and Spectral Characterization

Reaction of curcumin with K 2 PdCl 4 at pH 9.0 (60℃) produces a neutral complex of palladium containing curcumin as ligand. The compound was characterized by conductivity measurements, elemental analysis, infrared and UV-visible electronic spectroscopy and thermogravimetric analysis (TGA/DTA). The spectroscopic techniques show that the ligand is coordinated to palladium(II) via -diketone group. Thermal studies supported the chemical formulation of this complex and showed that the same has general structure [Pd(Cur-H) 2 ].2H 2 O.
