- Abstract
New gold(III) carboxylate complexes [(L)Au( RCO2)2]BF4 ( R = CH3, CMe3, CF3) with N, N-chelating ligands L (L = phenanthroline, 2, 2′-bipyridine), were obtained by the treatment of corresponding chloride complexes [(L)AuCl2]BF4 with silver(I) carboxylates. The structure of [(bipy)Au(CF3CO2)2]BF4 complex was determined by X-ray diffraction analysis. When five-coordinate gold(III) complexes [(L)AuCl3] (L = 2, 9-dimethyl-1, 10-phenanthroline, 2, 2′-biquinoline) were used as starting materials the same reaction led to unstable products, which could not to be isolated and characterized. The reactivity of chloride complexes towards different carboxylates as well as properties of resulting carboxylate compounds depends on the nature of substitute R in carboxylate groups as it was predicted by us earlier using quantum-chemical calculations. In order to explain a difference in behaviors of four- and five-coordinate gold(III) complexes infrared and far-infrared spectra of chlorides and carboxylates were studied.
