Halogenated gold(III) complexes containing 4-cyanopyridine: Synthesis, characterization, and crystal structure

چکیده مقاله

[Au(CN-py)Cl₃] complex (1) and [Au(CN-py)Br₃] complex (2) (CN-py is 4-cyanopyridine) were prepared from the reaction of 4-cyanopyridine with HAuCl₄.3H₂O and AuBr₃ in acetonitrile, respectively. Both complexes were characterized by IR, UV-Vis, ¹H NMR, and¹³C NMR spectroscopy and their structures were studied by the single-crystal X-ray diffraction method. Intermolecular C-H.Cl hydrogen bonds and Au.Cl contacts in the crystal structure of complex 1 and intermolecular C-H.Br hydrogen bonds and Au.Br and Br.N contacts in complex 2 effectively stabilize these complexes in their crystal structure.
