Abstract
In the present study, an Au(III) complex of caffeine (CA) and nicotinamide (NA) was synthesized under refluxing conditions. The preparation and structural elucidation of the complex were investigated by using physicochemical, and spectroscopic methods (UV/Vis, LC-MS, FT-IR, 1H and 13C NMR, XRD) and thermal analysis. The spectral measurements of mixed ligand complex of CA and NA with the Au(III) suggested that atoms of the ligands are coordinated to gold ion. Based on spectral and magnetic moment measurements, the complex was identified as in square-planar structure. From these analyses, it is predicted that the complex has the form of [Au(CA)2(NA)2]Cl3.2H2O.
