Synthesis and structural characterization of gold(III) dioximates with anions [AuCl4](-) and [AuCl2](-)

摘要

Two complexes of Au(III) with dimethylglyoxime of compositions [Au-III(HDMG)(2)][(AuCl4)-Cl-III] (1) and [Au-III(HDMG)(2)][(AuCl2)-Cl-I] (2) were synthesized and characterized by X-ray structural analysis. It was shown that in [Au-III(HDMG)(2)](+) cation Au(III) has a square-planar environment, and the oxygen atoms of oxime groups are joined by intramolecular H-bond. The secondary (AuAu)-Au-. . . and (AuCl)-Cl-. . . interactions in the crystal are discussed. (c) 2005 Elsevier B.V. All rights reserved.
