The reaction of AuCl(3)py with Na(pz*) (pz* = pyrazolato, or substituted pyrazolato anion) yields stable dinuclear [cis-(AuCl2)-Cl-III(mu-pz*)](2) complexes. In the presence of a base, the latter undergo reduction with concomitant transformation of the dinuclear Au-2(III)-structure to trinuclear (Au2AuI)-Au-III, (AuAu2I)-Au-III (containing trans (AuCl2)-Cl-III-centres) and Au-3(I) species.
