Two complexes of gold of the compositions [Au(DMG)ClPy] (1) and [AuCl2Py2][AuCl4] · 2[AuCl3Py] (2), where H2DMG was dimethylglyoxime, were synthesized as the products of interaction of H[AuCl4] · 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.
The interaction of H[AuCl4] · 4H2O with dimethylglyoxime (H2DMG) in the presence of pyridine at different synthetic conditions results in new coordination compounds of gold(III): [Au(DMG)ClPy] and [AuCl2Py2][AuCl4] · 2[AuCl3Py]. X-ray structural analysis showed that stabilization of molecular or ionic complex is achieved through Au⋯Cl intermolecular interactions which define the crystal architecture.Figure optionsDownload as PowerPoint slide
