Abstract :Auinsert ignore into journalissuearticles values(III);-caffeine complex was synthesized and characterized by means of solid-state linear-dichroic infrared spectral analysis insert ignore into journalissuearticles values(IRLD);, 1H-NMR, MS, DSC and TGA methods. The caffeine insert ignore into journalissuearticles values(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 Auinsert ignore into journalissuearticles values(III); coordination sphere are occupied by Cl-, thus forming [Au3+insert ignore into journalissuearticles values(C8H10N4O2);Cl3] complex. IR-characteristic band assignment in the 4000-400 cm-1 IR region of pure ligand and corresponding Auinsert ignore into journalissuearticles values(III);complex was performed.
