Synthesis and Characterization of Copper Complex Chelated with Phenobarbital Ligand

Abstract:

The research is intended to synthesize copper(II) with Phenobarbital (PB) complex in 1 : 4 mole ratio. The sole reflux method is designated to synthesize reactant within methanol solvent. Cu(II) complex is characterized using Atomic Absorption Spectrophotometry (AAS), UV-Vis Spectrophotometer, Fourier-transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), Conductivity meter, and Magnetic Susceptibility Balance (MSB). The Cu(II)-PB complex signified 1 absorption peak at 517.5 nm with 2Eg → 2T₂g transition. Complex is then composed by 6 electron donors of Cu ion-bound ligand, forming the octahedral geometry. Complex possesses the molecule formula of [Cu(PB)₃]Cl₂, this signifies only the PB that bound to Cu(II) ion as ligand through Oxygen and Nitrogen atom donors. There is no evidence of H₂O molecules coordinated as ligand. Complex is electrolyte along with Cl^- as counter ion that neutralized the complex charge. Complex is also being paramagnetic with the value of μeff of 1.74 BM.
