Abstract :In the present study, an Auinsert ignore into journalissuearticles values(III); complex of caffeine insert ignore into journalissuearticles values(CA); and nicotinamide insert ignore into journalissuearticles values(NA); was synthesized under refluxing conditions. The preparation and structural elucidation of the complex were investigated by using physicochemical , and spectroscopic methods insert ignore into journalissuearticles values(UV/Vis, LC-MS, FT-IR, 1 H and 13 C NMR, XRD); and thermal analysis. The spectral measurements of mixed ligand complex of CA and NA with the Auinsert ignore into journalissuearticles values(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 [Auinsert ignore into journalissuearticles values(CA); 2 insert ignore into journalissuearticles values(NA); 2 ]Cl 3 .2H 2 O.
