Abstract
Au(III)-caffeine complex was synthesized and characterized by means of solid-state linear-dichroic infrared spectral analysis (IRLD), 1H-NMR, MS, DSC and TGA methods. The caffeine (I) is monodentate and coordinated with metal ion through its N9 atom at molar ratio metal to ligand 1:1. The other 3 positions in the Au(III) coordination sphere are occupied by Cl-, thus forming [Au3+(C8H10N4O2)Cl3] complex. IR-characteristic band assignment in the 4000-400 cm-1 IR region of pure ligand and corresponding Au(III)complex was performed.
