Abstract:	Two complexes of gold of the compositions Au(DMG)ClPy] (1) and AuCl₂Py₂]AuCl₄] · 2AuCl₃Py] (2), where H₂DMG was dimethylglyoxime, were synthesized as the products of interaction of HAuCl₄] · 4H₂O with H₂DMG in the presence of pyridine and characterized by X-ray structural analysis. It was shown that depending on the synthetic conditions, the final product represents a molecular complex 1 or an ionic complex 2, in the latter one the charged and neutral species being combined via Au?Cl or Au?Au interactions.

Keywords:	Au(III) Crystal structure Au?Cl and Au?Au interactions
