Abstract
The reaction of gold(III) neutral complexes AuBr(CN)2(N–N) {N–N = 2,20-bipyridine (bpy), 5,50- dimethyl-2,20-bipyridine (Me2bpy), 1,10-phenanthroline (phen)} with a stoichiometric amount of K[AuCl4] 2H2O in nitromethane at room temperature led to the formation of 1:1 electrolytes which were characterized by NMR and IR spectroscopy, conductivity measurements, elemental analyses and X-ray diffraction. Both the anions and the cations of these salts are singly charged square-planar Au(III) complexes and the cations have general formula [AuCl2(N–N)]+. A hypothesis on the possible reaction mechanisms is presented to give an explanation for the formation of the reaction products.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
